Question

use substitution so solve 3x+4y=-3 x+2y=-1

Answer 1

please help

Answer 2

I can help you out on this one buddy. :)

Answer 3

please do

Answer 4

Firstly, you isolate y in your first equation in the goal of replacing it in your second equation.

Answer 5

4y=-3x-3
y=(-3x-3)/4

Answer 6

Then you replace the new y value into the second equation.

Answer 7

Try that and mention me when you think you found an answer.

Answer 8

I got you.

Line them up together and use the elimination method.

3x+4y=-3
x+2y=-1

Multiply the last one by 3.

3x+4y=-3
3x+6y=-3

Subtract.

-2y=0

Therefore, y=0.

Then, to get x, put the y which is 0, to the 2nd equation.

x+2(0)=-1

x=-1
