Answer:

x=

-12

Step-by-step explanation:

Simplifying

3x + -9 = 5x + 15

Reorder the terms:

-9 + 3x = 5x + 15

Reorder the terms:

-9 + 3x = 15 + 5x

Solving

-9 + 3x = 15 + 5x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-5x' to each side of the equation.

-9 + 3x + -5x = 15 + 5x + -5x

Combine like terms: 3x + -5x = -2x

-9 + -2x = 15 + 5x + -5x

Combine like terms: 5x + -5x = 0

-9 + -2x = 15 + 0

-9 + -2x = 15

Add '9' to each side of the equation.

-9 + 9 + -2x = 15 + 9

Combine like terms: -9 + 9 = 0

0 + -2x = 15 + 9

-2x = 15 + 9

Combine like terms: 15 + 9 = 24

-2x = 24

Divide each side by '-2'.

x = -12

Simplifying

x = -12

How to use substitution to solve system of equations
svlad2 [7]

Answer: See explanation.

Step-by-step explanation:

Let's assume that you have a System of two equations. You can solve this System using the Substitution Method.

In order to use that method to solve the System of equations, you can follow the steps shown below:

Step 1: You must choose one of the equations of the system and solve for one of the variables. Let's call this new equation "Equation A"

Step 2: Then you must substitute"Equation A" into the other equation.

Step 3: Now you must solve for the other variable in order to find its value.

Step 4: Finally, you need to substitute the value of the variable obtained in the previous step, into the "Equation A" and then evaluate in order to find the value of the other varibale.

(Note: You can also substitute the value of the variable calculated in Step 3 into any original equation and solve for the other variable to find its value).
