Question

5.m + 3 = 18 resolver
x+ 5= 25 resolver
x + 12 (signo mayor o igual que) 10 resolver
2.x <14 resolver

Answer 1

$5 \times m + 3 = 18 \\ 5m + 3 = 18 \\ 5m = 18 - 3 \\ 5m = 15 \\ m = 15 \div 5 \\ m = 3$

$x + 5 = 25 \\ x = 25 - 5 \\ x = 20$

$x + 12 > 10 \\ x > 10 - 12 \\ x > - 2$

$2 \times x < 14 \\ 2x < 14 \\ x < 14 \div 2 \\ x < 7$
espero haberte ayudado
