Question

It’s due tomorrow plz HELP

Answer 1

1)

`(3)/(4) + 5 - (1)/(2) = (3)/(4) + (20)/(4) - (2)/(4) = (21)/(4) = 5 (1)/(4)`

2)

`(2)/(3) + {2}^(3) - (1)/(3) = (2)/(3) + (24)/(3) - (1)/(3) = (25)/(3) = 8 (1)/(3)`

3)

`- 15 + 6x - 19 - 20x = - 14x - 34`

4)

`- 7x - 2 - 9y + 10x = 3x - 9y - 2`

5)

`14 + x = 18 \\ x = 18 - 14 \\ x = 4`

6)

`- 5x = - 15 \\ x = - 15 / ( - 5) \\ x = 3`

7)

`- 2x + 8 = 18 \\ - 2x = 18 - 8 \\ - 2x = 10 \\ x = 10 / ( - 2) \\ x = - 5`

8)

`3x + 18 - 8x = - 17 \\ 3x - 8x = - 17 - 18 \\ - 5x = - 35 \\ x = - 35 / ( - 5) \\ x = 7`
