Question

how do i solve the 2 step equations

45-m/30=165

Answers

Brianna
45-m/30 = 165
*30 *30
-----------
45-m = 4950
-45 -45
-----------
-m = 4905
divide by -1 on both sides

m= -4905
Brianna
so first you multiply both sides by 30


then you subtract 45 from both sides

and then divide by -1 on both sides

45-m/30 = 165

Multiply both sides by 30

45-m = 4 950

Subtract 45 from both sides

-m = 4905

M cannot be negative so change signs on both sides.



m = -4905

Now if you plug in what m equals you should get 165

45-(-4905)/30=165
sara
45 - m divided by 30 =165

What don't you get about the explanation?

it came out 6300 in my caculater

One way to check your answer is to plug what m equals into your original equation

(45 - 6300)/30 = 165

That is a false statement.
