Question

4(m+5) – m = 5m -8
2(t – 6) +2t = t + 27:(-9)
3( 4 x -4) = 2(3x -5) +4

Answer 1

$4(m + 5) - m = 5m - 8 \\ 4m + 20 - m = 5m - 8 \\ 3m + 20 = 5m - 8 \\ 20 + 8 = 5m - 3m \\ 28 = 2m \\ 14 = m$

$2(t - 6) + 2t = t + 27 \div ( - 9) \\ 2t - 12 + 2t = t + ( - 3) \\ 4t - 12 = t - 3 \\ 4t - t = - 3 + 12 \\ 3t = 9 \\ t = 3$

$3(4x - 4) = 2(3x - 5) + 4 \\ 12x - 12 = 6x - 10 + 4 \\ 12x - 12 = 6x - 6 \\ 12x - 6x = - 6 + 12 \\ 6x = 6 \\ x = 1$
