x = 18 and x = -

Step-by-step explanation:

1

- 4 + = - 10 ( add 4 to both sides )

= - 6 ( multiply both sides by - 3 to clear the fraction )

x = 18

As a check

Substitute x = 18 into the left side of the equation and if equal to the right side then it is the solution.

- 4 + = - 4 - 6 = - 10 = right side

Thus x = 18 is the solution

2

- 2x + 3 = 4 ( change mixed numbers to improper fractions )

- 2x + = ( multiply through by 4 to clear the fractions )

- 8x + 14 = 19 ( subtract 14 from both sides )

- 8x = 5 ( divide both sides by - 8 )

x = -

As a check

- 2 × - + 3

= + 3

= 1 + 3

= 4 = right side

Thus x = - is the solution
