Exercise

Solve the following equation. $- \frac{5}{2} = \frac{3}{4} z + \frac{1}{2}$

Answer

$z = - 4$

Hint

Solution

To solve the equation, we need to transfer the

z

terms to one side and the constant terms to the other.

- \frac{5}{2} = \frac{3}{4} z + \frac{1}{2}

$VL - \frac{1}{2} = HL - \frac{1}{2}$

- \frac{6}{2} = \frac{3}{4} z

Beräkna kvot

- 3 = \frac{3}{4} z

$VL / 3 = HL / 3$

- 1 = \frac{1}{4} z

$VL \cdot 4 = HL \cdot 4$

- 4 = z

Omarrangera ekvation

z = - 4

The solution of the equation then is

z = - 4 .
