It seems to be some kind of simultaneous equation with too many equality signs in it.
if it is -X then X=5 if it was minus X the X=10
-4x-1-3x-4+5 = -7x-1-2x+1+6 -7x = -9x+6 2x = 6 x = 3
y + 4 = 2x −1
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.
x=3/2
x=1
{-1,-2}
x = 0
If: 2x+5y = 2 and -3x-y = -3Then it works out that: x = 1 and y = 0
-2x plus 3y equals 1
Minus one half, (-1/2).
