Question

Solucione las siguientes ecuaciones según corresponda al caso:
X + 17 = -18
15m = -225
3x + 5 = 2x – 8
3x + 5 – 8x + 2 = 6x - 1

Answer 1

PROCEDIMIENTOS:

x + 17 = -18

x = -18 - 17

x = -35

15m = -225

15m ÷ 15 = -225 ÷ 15

m = -15

3x + 5 = 2x – 8

3x - 2x = -8 - 5

x = -13

3x + 5 – 8x + 2 = 6x - 1

-5x + 7 = 6x - 1

-5x - 6x = -1 - 7

-11x = -8

x = $\frac{8}{11}$
