Step 3: Combine the equations to solve.
b = j + 13
b + 3 = 2(j + 3)
Since the question asks to solve for j, you should substitute (j + 13) for b in
the second equation.
(j + 13) + 3 = 2(j + 3)
j + 16 = 2j + 6
10 = j

x is 5 greater than y x = 5 + y x + 5 = y
x is 5 less than y x = y – 5 x = 5 – y
x is half of y x =^12 y x = 2y
x is twice y x = 2y x =^12 y
