Help me. The topic is Maths, please.

Answer 1

Answer:

7

3

Step-by-step explanation:

First Solution

X=7

4= 12

Making X Subject of the formula

we have,

X= 7×4 = 28 = 14 = 7

12 12 6 3

OR

You cross multiply

X multiplies 12= 12X

7 multiplies 4= 28

you now have 12X=28

divinding both sides by 12,

12 cancels 12 and leave X

Answer 2

Answer:

x = $\frac{7}{3}$

Step-by-step explanation:

$\frac{x}{4}$ = $\frac{7}{12}$ ( cross- multiply )

12x = 28 ( divide both sides by 12 )

x = $\frac{28}{12}$ = $\frac{7}{3}$ ← in simplest form
