Answer:
a = 6 b= 7
Step-by-step explanation:
4 (b-1) = 3b + 3 substitue for a
4b - 4 = 3b + 3 subtract 4b from both sides
-4 = 3b + 3 - 4b = -4 = -b + 3 combine 3b and (-4b)
-7 = -b divide by -1 for both sides
7 = b
4a = 3 × 7 + 3 substitute for b
4a = 24 combine like terms
a = 6 divide by 4 on both sides
a = 7 -1
a = 6
