Question

resolver esta ecuacion es urgente

A: 3m+2-5m=7+m-12m
B: 4(2y-3)+7y=5(8+2x)+3
ayudaaaa

Answer 1

Explicación paso a paso:

A:

$3m + 2 - 5m = 7 + m - 12m \\ - 2m + 2 = 7 - 11m \\ - 2m + 11m = 7 - 2 \\ 9m = 5 \\ m = \frac{5}{9} = 0.56$

B:

$4(2y - 3) + 7y = 5(8 + 2x) + 3 \\ 8y - 12 + 7y = 40 + 10x + 3 \\ 15y - 12 = 43 + 10x \\ 15y - 10x = 55 \\ 3y - 2x = 11 \\ \\ x = \frac{11 - 3y}{2} \\ \\ y = \frac{11 + 2x}{3}$
