Question

7m − 4 − 9m − 36 = 0

Answer 1

Answer:

-20

Step-by-step explanation:

7m − 4 − 9m − 36 = 0

-2m - 4 - 36 = 0

-2m - 40 = 0

-2m = 40

m = -20

Answer 2

Answer:

The answer is $m=-20$

Step-by-step explanation:

In order to determine the answer, we have to know about solving equations.

When we have to solve an equation of one variable, first we have to add similar terms. A term is just a variable with a coefficient. Similar terms have the same variable.

In this case, we have two terms:

1. "m" variable.
2. just a number.

Then we have to solve the variable "m". We have to free it in one side.

Adding similar terms:

$7m-4-9m-36=0\\-2m-40=0\\-2m=40\\m=-\frac{40}{2}\\ \\m=-20$

Finally, the answer is $m=-20$
