Question

Me podrían ayudar por favor?

Answer 1

$5(2x - 7) = 8 \\ 10x - 35 = 8 \\ 10x = 8 + 35 \\ x = \frac{43}{10} \\ \\ x = 4.3$

$3(2x + 1) = 30 \\ 6x + 3 = 30 \\ 6x = 30 - 3 \\ \\ x = \frac{27}{6} \\ \\ x = 4.5$

$8(2x - 12) = 24 \\ 16x - 96 = 24 \\ 16x = 24 + 96 \\ \\ x = \frac{120}{16} \\ \\ x = 7.5$
