3b -2 =7 b+4
-7+3b = 4b-8 3b-4b = -8+7 -b = -1 b = 1
It is a linear equation in two unknown variables, a and b. It can be simplified (slightly) but cannot be solved becasue to solve with two unknowns you need two independent equations. Incidentally, a + 5 = (a - 7) + 12 = (3b + 2) +12 = 3b +14
-45m + 68 = 84m - 61 39m = 7 m = 7/39
3b - 7b - 2 = 26 then , -2 - 4b = 26 then , 4b = 26 then you do , -4 / 26 which equals 7
