1. x = 5
2. x = 4

Answer 2

a)

By cross multiplication

`(3x + 4)/(2) = 9.5 \\ \\ 3x + 4 = 9.5 * 2 \\ \\ 3x + 4 = 19 \\ \\ 3x = 19 - 4 \\ \\ 3x = 15 \\ \\ x = (15)/(3) \\ \\ { \underline{x = 5}}`

b)

`(7 + 2x )/(3) = 5 \\ \\ 7 + 2x = 5 * 3 \\ \\ 7 + 2x = 15 \\ \\ 2x = 15 - 7 \\ \\ 2x = 8 \\ \\ x = (8)/(2) \\ \\ { \underline{x = 4}}`
