If `3x + 20 = 65`, then find the value of x

Text Solution

Verified by Experts

The correct Answer is:
`x = 15`
step:1 Group the known quantities as the RHS of the equation, i.e., `3x = 65 - 20`
Step2: Simplify the numbers on the RHS. `rArr 3x = 45`
Step 3: Since 3 is the coefficient of x, divided both sides of the equation by 3.
`(3x)/(3) = (45)/(3) rArr x = 15`
