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.
