4x=-10 x=-2.5
y=4x-8y=2x+10Substitute (4x-8) for y in the second equation and solve for x:4x-8=2x+102x=18x=9Now solve for y:y=4(9)-8=28(9,28)
2y = 4x + 4y = 2x + 2
x=5

x= -.5
You can't solve it. But you can simplify it to get: 4x+y=2
6x + 10 + 4x = 5010x + 10 = 5010x = 40x = 4
4x - 10 = -4x + 22 +4x+10=+4x +10 8x = 32 x = 4
4x-3+2x-x = 10 Collect the like terms; 5x-3 = 10 5x = 13 x = 13/5
4x-y=2, thereforey=4x-2sub y into 3x+2y=6...3x+8x-4=611x=10x=10/11
8x + 10 = 3x +145x = 4x = 4/5 = 0.8Improved answer:8x+10 = 4x+148x-4x = 14-104x = 4x = 1
