- Step1: Using LCM, clear the fractions if any.
- Step2: Simplify both sides of the equation.
- Step 3: Isolate the variable.
According to the given question
We have, a linear equation in variable r.
2r +7 =16
⇒ 2r + 7 -7 = 16 -7
⇒ 2r = 9
⇒ r = 9/2
Hence, the value of r is 9/2 for the given linear equation 2r + 7 = 16.
