Question 690531
Let A = X
Let B = X + 1
------------
{{{(4/6)X - 12 = (1/3)*(X+1)}}}
Lets eliminate the fractions by multiplying everything by 6
{{{4X - 72 = 2*(X + 1)}}}
Simplify
{{{4X - 72 = 2X + 2}}}
Subtract 2X from both sides
{{{2X - 72 = 2}}}
Add 72 to both sides
{{{2X = 74}}}
Divide both sides by 2
{{{highlight(X = 37)}}}
{{{highlight_green(A = 37)}}}
B = X + 1
{{{highlight_green(B = 38)}}}
