Answer:
C. x = 12
Step-by-step explanation:
5(12) + 9 = 69 - 3(12) = 33
18 + 15 = 33
Answer: x = 12
Step-by-step explanation:
The given equation is expressed as
5х+9 - 3х= 18 + 15
5x - 3x + 9 = 33
2x + 9 = 33
The first step is to make the terms each term containing x to be on the left hand side of the equation and the constants to be on the right hand side of the equation. Therefore, we would subtract 9 from the left hand side and the right hand side of the equation.
It becomes
2x + 9 - 9 = 33 - 9
2x = 24
Dividing the left hand side and the right hand side of the equation by 2, it becomes
2x/2 = 24/2
x = 12
