Question

1. 3x + 5 = 20
2. 4( 2x − 3) = 108
3. − {4 + [3 (2x - 5) + 16 (2x - 4)} = 16
4. - { - [3(8x + 4)] + 9 (2x - 5) } = 114
5. -5 [(3x - 9)] - 6[ 2x + 4(8x -9)] + 7} = 23
6. 7/2x + 5 - 3[ + 7(4x + 9)] - 16] = 48
7. 14(3x + 16) - 12(4x - 5) = 130
8. 9(3x - 15) = 4x(7 - 5)
9. 24(3x - 16) = 28 - 4x
10. 5 - { - [4 (3x + 18) - 5(2x + 3)] + 9 } = 29
