36

Step-by-step explanation:

Step 1:

1/2 ( 12x - 36 ) = 5x + 18   Equation

Step 2:

6x - 18 = 5x + 18   Multiply

Step 3:

x - 18 = 18   Subtract 5x on both sides

x = 36   Add 18 on both sides

Hope This Helps :)

x = - \frac{5}{22}

Step-by-step explanation:

4 - \frac{2(x - 4)}{3} = \frac{3(2x + 5)}{2}

➡️ 4x - \frac{2x - 8}{3} = \frac{6x + 15}{2}

➡️ 24 - 2(2x - 8) = 3(6x + 15)

➡️ 24 - 4x + 16 = 18x + 45

➡️ 40 - 4x = 18x + 45

➡️ - 4x - 18x = 45 - 40

➡️ - 22x = 5

➡️ x = - \frac{5}{22}
