Answer 1

Answer:

x = -1

Step-by-step 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 =

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.

The value of x is -1.

Step-by-step explanation:

Simple equation:

☆Let's solve!

$15 = - 5x + 10 \\ \frac{ - 10 = \: \: \: \: \: \: \: \: - 10}{ \frac{5}{ - 5} = \frac{ - 5x}{ - 5} } \\ x = - 1$
