Question

equation 10y+20= 100

Answer 1

10y + 20 = 100

⇒ 10y = 100 - 20

⇒ 10y = 80

∴ y = 8

Answer 2

In accordance with the information provided in the question,

We have find the value of the supplied expression in the above question.

Given the data in question  10y+20= 100

Hence, for solving the above equation, we will solve it by separating the like terms at one side.

So, we will shift 20 from LHS to RHS,

So, we will get it as,

$10y+20=100\\10y=100-20\\10y=80\\y=\frac{80}{10} \\y=8$

Hence, value of "y" in above equation will be $8$.
