Answer:
r= -20
Step-by-step explanation:
you need to solve this equation for the variable r, which means you need to get r alone on one side of the equation.
4r-8=5r+12
subtract 4r from both sides
-8=5r-4r+12
-8=1r+12
subtract 12 from both sides
-8-12=r
simplify
-20=r
The value of r is -20.
Given: Equation
4r - 8 = 5r + 12
We have to find the value of r.
⇒ 4r - 8 = 5r + 12
⇒ 5r - 4r = -12 - 8
⇒ r = -20
Therefore, the value of r in the given equation is -20.
