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
