Answer:
Step by step:
4/5a - 8 = a + 2
Start off by subtracting 4/5a from each side to get the variable only on one side
-8 = 1/5a + 2
Now subtract 2 from both sides to get the variable by itself
-10 = 1/5a
Now flip 1/5 upside down to multiply it by each side to get rid of the coefficient
-10 5 5 1
—— •—— = —- •—- a
1 1 1 5
(The 5/1 and 1/5a cancel each other out leaving a alone)
-50
—— = a
1
Now turn -50/1 into a whole number
-50 = a
Now flip the equation so a is on the right
A = -50
