Question

Choose a variable to isolate and what it is equal to in the system of equations below.
12x=2y-18
4y=3x-1
a.y=6x-9
b.x=6y-9
c.y=6x+9
d.y=x-9

Answer 1

Isolate variable
4y=3x-1
y = (3x - 1)/4
sub y into the other equation

12x=2((3x - 1)/4)-18
solve for x

sub x into one of the original equations to solve for y
