Solve the equation for the unknown variable 5(x+5)=10

x= -3

Step-by-step explanation:

Given: 5(x+5) = 10

Find: x

Set the equation up.

5(x+5) = 10

Simplify.

5x + 25 = 10

Subtract 25 from both sides.

5x = -15

Divide to isolate the variable.

x = -3.

x = -3

Step-by-step explanation:

Lets start simplifying:

Method 1:

5(x+5) = 10      Multiply parenthesis by 5

5x+25 = 10     Subtract 25 from both sides

5x = -15           Divide by 3 on both sides

x = -3

Method 2:

5(x+5) = 10     Divide by 5 on both sides

x+5 = 2           Subtract 5 from both sides  

x = -3
