Answer 1

The value of x is -1.

Explanation:

Simple equation:

☆Let's solve!

`15 = - 5x + 10 \\ ( - 10 = \: \: \: \: \: \: \: \: - 10)/( (5)/( - 5) = ( - 5x)/( - 5) ) \\ x = - 1`

Answer 2

x = -1

Explanation:

15 = -5x + 10

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operations, and =

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

First, subtract 10 from both sides of the equation:

15 (-10) = -5x + 10 (-10)

15 - 10 = -5x

-5x = 15 - 10

-5x = 5

Next, fully isolate the x by dividing -5 from both sides:

(-5x)/-5 = (5)/-5

x = -(5/5)

x = -1

-1 is your answer for x.
