[tex]6(x - 4) - 2 = 6x - 24 - 2 = 6x - 26[/tex]
[tex]2(x + 1) - 3(x - 1) = 2x + 2 - 3x + 3 = - x + 5[/tex]
[tex] - 3(y - 2) + 4(y + 2) = - 3y + 6 + 4y + 8 = y + 14[/tex]
[tex]5(x - y - 1) - 4(x + 2) = 5x - 5y - 5 - 4x - 8 = x - 5y - 13[/tex]
[tex]2(3a + b) - 2(a - b) = 6a + 2b - 2a + 2b = 4a + 4b[/tex]
[tex] \frac{1}{2} (4x - 4) - 2x = 2x - 2 - 2x = - 2[/tex]
[tex]x(x - 1) - 3( {x}^{2} - x) = {x}^{2} - x - 3 {x}^{2} + 3x = - 2 {x}^{2} + 2x[/tex]
[tex]5a(a - 3) - 3a(a - 5) = 5 {a}^{2} - 15a - 3 {a}^{2} + 15a = 2 {a}^{2} [/tex]
