Question

question 2: solve the following equations
(i) $\frac{x}{4}=1.6$
(j) $\frac{x}{2.5}=8$
(k) $\frac{x}{4}=-3$
(l) $\frac{x}{6}=-12$

Explanation:

Step1: Isolate x for (i)

Multiply both sides by 4.
$x = 1.6\times4$
$x = 6.4$

Step2: Isolate x for (j)

Multiply both sides by 2.5.
$x=8\times2.5$
$x = 20$

Step3: Isolate x for (k)

Multiply both sides by 4.
$x=-3\times4$
$x=-12$

Step4: Isolate x for (l)

Multiply both sides by 6.
$x=-12\times6$
$x = - 72$

Answer:

(i) $x = 6.4$
(j) $x = 20$
(k) $x=-12$
(l) $x=-72$
