Question

Find the solution to the system of equations.

please explain <3

Answer 1

D)

Explanation:

y= -x+2

y= 3x -4

Multiply y= -x +2 by 3 so we get:

3y=-3x +6

y= 3x -4

Then, we can use elimination to cancel the x and get:

3y= 6

y= -4

Add the y together as well as the 6 and -4 to get:

4y= 2

Then we get y= 1/2

Plug y= 1/2 into y= 3x -4 to get:

1/2= 3x -4

Add 4 to both sides to get:

4+(1/2)= 3x

4.5=3x

x=1.5 or 3/2

Hope this helps. Sorry its long.
