Question

set up equations and solve them to find the unknown numbers in the following cases : If I take three-fourths of a number and add 3 to it,I get 21​

Answer 1

Answer:

$\frac{3}{4}$ X no. + 3 = 21

Step-by-step explanation:

"Of" means multiply so,

$\frac{3}{4}$ X no.

Add 3 to it that means

$\frac{3}{4}$ X no.+ 3

I get 21 that means the answer to the equation is 21 so we'll write it as-

$\frac{3}{4}$ X no.+ 3 = 21

Answer 2
