Question

Solve the system by substitution.
3x-6y=2
4x+3y=-1​

Answer 1

y = -1/3

x = 0

Explanation:

3x-6y = 2 then 3x = 2+6y, x=(2+6y)/3

4x+3y = -1

substitute for x

4(2/3+2y)-6y = 2

8/3+8y-6y = 2

reduce

2y = 2-8/3

2y = -2/3

divide both sides by 2

y = -1/3

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

4x = 0

x = 0
