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%
