Answer:
1.Solve for y in 2x+y=-3
y=-3-2x
2. Substitute y= -3 - 2x into 4x-2y=10
8x+6=10
3 Solve for x in 8x+6=10
x=1/2
4. Substitute x=1/2 into y = - 3 - 2x
y= -4
5. So you get...,
x=1/2
y=−4

You could estimate by doing 600x3=1800
(becasuse of the 0's in 600 it is easier to do 6*3=18 and then add two 0's to the end 1800)
then you simply multiple 640x3=1920
