-13=5(1+4m)-2m

- 13 = 5 (1 + 4 m) - 2 m

m = - 1

Solution steps

- 13 = 5 (1 + 4 m) - 2 m

Switch sides

5 (1 + 4 m) - 2 m = - 13

Expand

5 (1 + 4 m) : 5 + 20 m

5 + 20 m - 2 m = - 13

Add similar elements:

20 m - 2 m = 18 m

5 + 18 m = - 13

Move

5

to the right side

18 m = - 18

Divide both sides by

18

m = - 1
