how do i solve the 2 step equations


45-m/30=165

45-m/30 = 165

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

m= -4905

so first you multiply both sides by 30

then you subtract 45 from both sides

and then divide by -1 on both sides

sorry the spacing didn't workout when i posted it the first time

but you use opposite operations

Ms. Sue can you help me.

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

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.

To solve a two-step equation, follow these steps:

Step 1: Simplify both sides of the equation if possible.
In this equation, you can simplify it by multiplying both sides by 30 to get rid of the fraction:

(45 - m)/30 x 30 = 165 x 30.

This simplifies to:

45 - m = 4950.

Step 2: Solve for the variable.
To isolate the variable (m) on one side of the equation, subtract 45 from both sides:

(45 - m) - 45 = 4950 - 45.

This simplifies to:

- m = 4905.

To solve for m, multiply both sides of the equation by -1 to get the variable isolated:

(-1) x (-m) = 4905 x (-1).

This simplifies to:

m = -4905.

Hence, the solution to the equation 45 - m/30 = 165 is m = -4905.
