Question

x + 48 = 200 y - 27 = 15

2x + 25 = 75 5y - 35 = 115

5m - 3m - 20 = 110 2(x + 2) = 50

Answer 1

Explicación paso a paso:

$x + 48 = 200 \\ x = 200 - 48 \\ x = 152 \\ y - 27 = 15 \\ y = 15 + 27 \\ y = 42 \\ 2x + 25 = 75 \\ 2x = 75 - 25 \\ x = \frac{50}{2} \\ x = 25 \\ 5y - 35 = 115 \\ 5y = 115 + 35 \\ y = \frac{150}{5} \\ y = 30 \\ 5m - 3m - 20 = 110 \\ 2m = 110 + 20 \\ m = \frac{130}{2} \\ m = 65 \\ 2(x + 2) = 50 \\ 2x + 4 = 50 \\ 2x = 50 - 4 \\ x = \frac{46}{2} \\ x = 23$
