Answer:
a=−3
Step-by-step explanation:
Let's solve your equation step-by-step.
3(4a+4)=3a+8a+1+8
Step 1: Simplify both sides of the equation.
(3)(4a)+(3)(4)=3a+8a+1+8(Distribute)
12a+12=3a+8a+1+8
12a+12=(3a+8a)+(1+8)(Combine Like Terms)
12a+12=11a+9
Step 2: Subtract 11a from both sides.
12a+12−11a=11a+9−11a
a+12=9
Step 3: Subtract 12 from both sides.
a+12−12=9−12
(3,2) is the solution
