Question

Resolver las siguientes ecuaciones
1. X -36= -78
2. Y + 36 = 120
3. 2m - 8 = 16
4. 14 - x = -16
5. 1 - x = - 5

Answer 1

Explicación paso a paso:

$x - 36 = - 78 \\ x = - 78 + 36 \\ x = - 42$

$y + 36 = 120 \\ y = 120 - 36 \\ y = 84$

$2m - 8 = 16 \\ 2m = 16 + 8 \\ 2m = 24 \\ m = \frac{24}{2 } \\ m = 12$

$14 - x = - 16 \\ 14 = - 16 + x \\ 14 + 16 = x \\ 30 = x$

$1 - x = - 5 \\ 1 = - 5 + x \\ 1 + 5 = x \\ 6 = x$
