Answer:
Step-by-step explanation:
34=-11+7A
We move all terms to the left:
34-(-11+7A)=0
We add all the numbers together, and all the variables
-(7A-11)+34=0
We get rid of parentheses
-7A+11+34=0
We add all the numbers together, and all the variables
-7A+45=0
We move all terms containing A to the left, all other terms to the right
-7A=-45
A=-45/-7
A=6+3/7
X= 5 or -8
Add all the like terms and set it equal to 49, use quadratic formula or factoring.
