R = X( A + B)
R = AX + BX
AX = R - BX
A = (R - BX) / X
Its A.
Distribute 2 to (x + 6) and 3 to (x - 4)
2(x + 6) = 3(x - 4) + 5
The first step is to distribute on both sides
2x+12 = 3x-4 +5
We have to distribute to all terms inside the parentheses
x = 6,0
y = 0,12
90
Divide 72 by 4 you get 18 which is how many Ling baked with one scoop of flour. Then just add 18 to 72 and you get 90
