Решите уравнения: 7m - 11 = 10m +16 -2х + 16 = 5х + 30 11m - 7 = 22 + 5m

Question

Решите уравнения:

7m - 11 = 10m +16

-2х + 16 = 5х + 30

11m - 7 = 22 + 5m

Answer 1

7m - 11 = 10m +16  
7m-10m=16+11
-3m=27
m=27:(-3)
m=-9

-2х + 16 = 5х + 30  
-2х-5х=30-16
-7х=14
х=14:(-7)
х=-2

11m - 7 = 22 + 5m
11m-5m=22+7
6m=29
m=29:6
m=4 5/6
