10a-37=6a+51 -6a -6a subtract 6a from both sides and the 6a's cancel 4a-37=51 +37 +37 4a=88 /4 /4 a=22
-6a + 8 = 2 -6a = -6 a = 1
A=2

6a + 9 = ? a = 7 just replace a with 7 6(7) + 9 order of operations; multiply first 42 + 9 = 51
-6a + 8 = 2 -6a = -6 a = 1

6a + (7b - 4a - 8b) = (6a - 4a) + (7b - 8b) = 2a - b
6a-3=8a+11 -3-11=8a-6a -14=2a a=-7

6a + 4 = 5a - 2 means that 6a - 5a = -2 - 4 which gives a = -6
