Question

X = 4y - 2

x - 3y = 6
If you were going to solve this equation by substitution, what would your first step look like?
A) x - 4y - 2 = 6
B) 4y - 2 - 3y = 6
C) x - 12y - 6 = 6
D) x - 12y + 6 = 6

Answer 1

Answer: the answer is b

Explanation:

Answer 2

if

`x = 4y - 2`
then just insert that value of x into this equation

`x - 3y = 6`
so the equation will look like this

`(4y - 2) - 3y = 6`

`4y - 2 - 3y = 6`
so the answer is B.
