Question

What is the value of x, when -25(x - 4) = -55(x - 10)?

Answer 1

x= 15

Explanation:

Step 1- Distribute into the parenthesis

-25x-(-25)4= -55x-(-55)10

Step 2- Multiply to simplify

-25x+100= -55x+550

Step 3- Add -55x to both sides

-25x+100= -55x+550

+55x +55x

Step 4- Subtract 100 to both sides

30x+100= 550

-100 -100

Step 5- Divide both sides by 30

30x= 450

30 30

x= 15

Answer 2

-25(x - 4) = -55(x - 10)

-25x+100= -55x+550

-25x+55x=550-100

30x=450

x=15
