Answer:
x=19
Step-by-step explanation:
-4 (5 - x) + 7x = 189 Distribute
4x-20+7x=189 Combine Like Terms
11x-20=189 Add 20 To Both Sides
11x=209 Divide By 11
x=19
Answer: exactly one solution
Explanation: first we have to solve it. so in 2 + 6x = 3x + 3 we have to subtract 2 from both sides and we get 6x = 3x + 1. then, we subtract 3x from both sides and we get 3x = 1. we divide both sides by 3 and get x = 1/3, which is the only solution.
