Answer: Jason can substitute
into the equation. The left side of the equation must be equal to the right side of the equation.
Step-by-step explanation:
The equation
must be solved by calculating the value of the variable x:
Add like terms:

Divide both sides by -12:

Once Jason solves for x, he has to substitute
into the equation and simplify to check his answers.
If his answer is right, the left side of the equation will be equal to the right side of the equation.
Then:

is a solution of the equation.
Answer:

Answer:
hope this helps! :)
Step-by-step explanation:
4x=36
divide both sides of the equation by 4
4x / 4 = 36 / 4
Any expression divided by itself equals 1
x= 36 / 4
Calculate the quotient
36/4 = 9
<u>x=9</u>
