3b - 7b - 2 = 26 then , -2 - 4b = 26 then , 4b = 26 then you do , -4 / 26 which equals 7
Numerically, if the question looks like this:--(3a + 7b) - 8a - 4b + 2Then the answer is this:--3a - 7b - 8a - 4b + 2= -11a -11b + 2
The "answer" is the number that ' b ' must be in order to make the statement true.4b + 6 = -2Subtract 6 from each side of the equation:4b = -8Divide each side by 4 :b = -2
5b = 21 + 4b 5b - 4b = 21 + 4b - 4b b = 21
2(a + 4b)
