Question

como se resuelve (no su explicacion)
5y-7=32
4a+12=40
3b-21=54
10m+60=90​

Answer 1

Respuesta:

$5y - 7 = 32 \\ 5y = 39 \\ y = \frac{39}{5}$

$4a + 12 = 40 \\ 4a = 28 \\ a = \frac{28}{4} = 7$

$3b - 21 = 54 \\ 3b = 75 \\ b = \frac{75}{3} = 25$

$10m + 60 = 90 \\ 10m = 30 \\ m = \frac{30}{10} = 3$
