Question

Please help me on this

Answer 1

a. X=5

b. X=4

solution,

`a. \: \: (3x + 4)/(2) = 9.5 \\ \: \: or \: 3x + 4 = 9.5 * 2(cross \: multiplication) \\ \: \: or \: 3x + 4 = 19 \\ \: \: or \: 3x = 19 - 4 \\ \: \: or \: 3x = 15 \\ \: or \: x = (15)/(3) \\ \: x = 5`

`b. \: \: (7 + 2x)/(3) = 5 \\ \: \: or \: 7 + 2x = 5 * 3(cross \: multiplication) \\ \: \: or \: 7 + 2x = 15 \\ \: \: or \: 2x = 15 - 7 \\ \: or \: 2x = 8 \\ \: or \: x = (8)/(2) \\ \: \: x = 4`

Hope this helps..

Good luck on your assignment..
