Answer:

x=0

Step-by-step explanation:

Hi there!

\displaystyle\frac{2}{3} (6x+30)=5(x+4)-2x

Distribute 2/3 and 5 into the parentheses:

4x+20=5x+20-2x

Combine like terms:

4x-5x+2x=20-20\\-x=0\\x=0

I hope this helps!

Multiply all terms by 15
3x+3x= 10x+30

Combine like terms
6x=10x+30

Subtract 10x from both sides
-4x=30

Divide both sides by -4
x= -7.5

Final answer: -7.5
