Question

Solve each of the following equations:
1. 6 + 3x = 15
2. 3x - 4 = 32 + 7x
3. 2(x + 3) = 8 - 3(x - 4)
4. 7y - 3 = 3y + 17
5. 5(6 - X) + 1 = x + 1
6. 4 - (x - 3) = 6 - 4x
7. 3(7 - 2x) = 14 - 8(x - 1)
8. 2(x + 7) + 5x + 3 = 3(x + 1) + 6​

Answer 1

Answer:

$6 + 3x = 15 \\ 3x =15 - 6 \\ 3x = 9 \\ x = 9 \div 3 \\ = 3$
