Yes, it does.
Ex:
2 + 3 = 3 +2 => 5 = 5

For negative integers:
(-2) + (-3) = (-3) + (-2) => -5 = -5

Solve for x and y<br><br> 2x+7=3y-1
zlopas [31]
To solve for x and y, isolate each variable and simplify your equation:

Solve for x:
2x+7=3y-1 (Subtract 7 on each side)
2x=3y-8 (Divide by 2 on each side)
x=\frac{3y}{2} -4

Solve for y:
2x+7=3y-1
2x+8=3y (Add 1 on each side)
\frac{2x}{3} + \frac{8}{3}=y (Divide by 3)
y=\frac{2x}{3} + \frac{8}{3}
