It seems to be some kind of simultaneous equation with too many equality signs in it.

3x - 2x + 4 = 0 3x - 2x = -4 x = -4

X=7

4x - 7 = 2x + 5 2x - 7 = 5 2x = 12 x = 6.

(Y = -2x plus or minus any number) is parallel to (Y = -2x + 5) .

the answer is y minus 10 divided by 2.

y + 4 = 2x −1

-3X

6 - x + 7 - 3x - 5 = -2x - 10 ∴ x + 3x - 2x = 6 + 7 - 5 + 10 ∴ 2x = 18 ∴ x = 9

x=1

-4x-1-3x-4+5 = -7x-1-2x+1+6 -7x = -9x+6 2x = 6 x = 3

4+2x-2x+1=13+6 Combine like terms. (4+1=5; 2x-2x=0; 13+6=19) 5=19 This problem has no solution.

If: 2x+5y = 2 and -3x-y = -3Then it works out that: x = 1 and y = 0
