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
if [tex]x = 4y - 2[/tex] then just insert that value of x into this equation [tex]x - 3y = 6[/tex] so the equation will look like this [tex](4y - 2) - 3y = 6[/tex] [tex]4y - 2 - 3y = 6[/tex] so the answer is B.
