Equation: 7(3x-2)=133
Distribute: 21x-14=133
Add like terms: 21x=147
Divide by 21: x=7
Answer:
x=22
Step-by-step explanation:
4x+2+x+3x+2=180
collect like terms
4x+x+3x=180-(2+2)
8x=180-4
8x=176
make x the subject of the formula
x=176/8
x=22
The answer is D. I graphed it on Desmos Graphing Calculator and I've linked the screenshot.
