Answer 2

Hola!

A)

$18 + 5x + 8x = 51 + 2x - 22 \\ 5x + 8x - 2x = 51 - 22 - 18 \\ 11x = 11 \\ x = 1$

B)

$x + 61 + x = </strong><strong>100</strong><strong> + 11x \\ 61 - </strong><strong>100</strong><strong> = 9x \\ - </strong><strong>39</strong><strong> </strong><strong>= 9x \\ - \frac{</strong><strong>13</strong><strong>}{3} = x$

C)

$x -29+15x=36+3x \\x + 15x - 3x = 36 + 29 \\ 13x = 65 \\ x = \frac{65}{13} </strong><strong>\\ x = </strong><strong>5</strong><strong>$
