Answer:
13.4
Step-by-step explanation:
(9x+2) 119 to solve for x you need to isolate it so subtract 119 so the equation would look like this (9x+2) = -119. Once you do that you are going to subtract 2 from both sides of the equation (9x)= -121. And now you divide by 9 and you have your answer x= 13.4.
Answer: 7x + 261
Step-by-step explanation:
(5x + 252 + x + 5) + (x + 4)
5x + 252 + x + 5 + x + 4 (get rid of parenthesis)
7x + 261 (combine like terms)
