Answer:
a=1 or a=5
Step-by-step explanation:
 +4=6a−1
+4=6a−1
Step 1: Subtract 6a-1 from both sides.
 +4−(6a−1)=6a−1−(6a−1)
+4−(6a−1)=6a−1−(6a−1)
 −6a+5=0
−6a+5=0
Step 2: Factor left side of equation.
(a−1)(a−5)=0
Step 3: Set factors equal to 0.
a−1=0 or a−5=0
a=1 or a=5
(is it helpful rate me according to that
