If 4a + 4a+1 = 4(a+2) - 176, what is the value of a?
Solution
Correct Answer: Option A
4a + 4a+1 = 4(a+2) - 176
or, 4a+4a+1-4a+2= -176
or, 4a+4a.41-4a.42 = -176
or, 4a ×(1+4-16)=-176
or, 4a ×(-11)=-11×16
or, 4a=42
So, a=2
or, 4a+4a+1-4a+2= -176
or, 4a+4a.41-4a.42 = -176
or, 4a ×(1+4-16)=-176
or, 4a ×(-11)=-11×16
or, 4a=42
So, a=2
