How do i solve this problem

M+3=-m-1

First you have to get the variables on one side and numbers on the other

M+3=-m-1

lets add M to both sides

now its

2M+3=-1

now we have to get the tree onto the right side of the =

we subtract 3 from both sides

2M = - 4

now we undo the multiplication and do division

2 : 4 = 0.5 or 1/20

M + 3 = m - 1

+1 + 1

m + 4 = m

-m - m

4 = 0m

0 0

0 = m

There is no solution.
