What is the value of s in the equation 3 r equals 10 plus 5 s, when r equals 10? 4 8 100 200

alisha [4.7K]

Answer

Step-by-step explanation:

Given,

r = 10

Let's create an equation,

$3r = 10 + 5s$

plugging the value of r

$3 \times 10 = 10 + 5s$

Multiply the numbers

$30 = 10 + 5s$

Move 5s to L.H.S and change its sign

Similarly, Move 30 to R.H.S and change its sign.

$- 5s = 10 - 30$

Calculate

$- 5s = - 20$

The difference sign ( - ) should be cancelled on both sides

$5s = 20$

Divide both sides of the equation by 5

$\frac{5s}{2} = \frac{20}{5}$

Calculate

$s = 4$

The value of s is 4.

Hope this helps..

Best regards!!
