# Of the following options, what could be a possible first step in solving the equation 8x + 3 = 2x − 15? adding 8x to both

###### Question:

adding 8x to both sides of the equation

adding 15 to both sides of the equation

adding 3 to both sides of the equation

adding 2x to both sides of the equation

## Answers

B.Adding 15 to both sides of the equation.

A. Adding 8x to both sides wouldn't cancel anything out.

B. Adding 15 to both sides will cancel out 15 making it easier to solve for x.

C.Adding 3 to both sides will not cancel anything out.

D. Adding 2x to both sides won't cancel anything out.

subtract 2x on both sides

Step-by-step explanation:

[tex]\text{I don't know your answer choices, but general the first thing}\\\text{you would do is move the x variables to one side or the single variables}\\\text{Doign this will allow you to set up the equation to divide}\\\\\text{You need to find the x value, so having the x values on one side}\\\text{and the one values on the other side will allow you to solve for x}[/tex]

add 7x to both of the sides

adding 15 to both sides of the equation

Step-by-step explanation:

Find the possible first step in solving the equation [tex]8x+3 = 2x - 15[/tex]

To eliminate any variable or constant we always do opposite operation

adding 8x to both sides of the equation : Opposite of 8x is -8x, Subtract -8x to remove 8x

adding 15 to both sides of the equation: opposite of -15 is +15 so we add 15 on both sides

adding 3 to both sides of the equation: opposite of 3 is -3, so subtract 3 on both sides

adding 2x to both sides of the equation: opposite of 2x is -2x, so we subtract 2x on both sides

First you need to combine like terms.

3x+2x= 6x

-1+4=3

SO the answer will be,

6x+3.

its wrong

Step-by-step explanation:

its sub 5

Note that in this equation, you are solving for x.

The first step i would take is "isolating the x". To do so, add 1 to both sides, and subtract 2x from both sides

3x (-2x) - 1 (+1) = 2x (-2x) + 4 (+1)

3x - 2x = 4 + 1

x = 5

hope this helps

Option a) Adding 7x to both the sides

Step-by-step explanation:

Given is an equation linear in one variable x.

[tex]-7x -5= x + 3[/tex]

To solve this equation we have to bring x terms on one side and constants on the other side.

Subtracting 5 from both sides will not eliminate the constant -5 hence wrong.

Adding x to both sides will make right side as 2x instead of eliminating x.

Combining like terms will give -7x-x not -7x+x hence incorrect

Adding 7x to both sides gets rid of x term on the left.

Hence this option is right answer

Subtracting 2x from both sides of the equation

Step-by-step explanation:

This is correct i just took the test and got 100%
