Answer:
a=10
Step-by-step explanation:
11a-(4a-7)=77
11a-4a+7=77
7a+7=77
7a=70
a=10
Answer:
a=10
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
11a−(4a−7)=77
11a+−1(4a−7)=77(Distribute the Negative Sign)
11a+−1(4a)+(−1)(−7)=77
11a+−4a+7=77
(11a+−4a)+(7)=77(Combine Like Terms)
7a+7=77
Step 2: Subtract 7 from both sides.
7a+7−7=77−7
7a=70
Step 3: Divide both sides by 7.

Thus a = 10
