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