2r = 48 + 4r
2r - 4r = 48
-2r = 48
etc
2r - 4r = 48
-2r = 48
etc
Step 1: Start by distributing the 4 to both terms on the right side of the equation:
2r = 48 + 4r becomes 2r = 48 + 4r
Step 2: Combine like terms:
2r - 4r = 48
Step 3: Simplify the left side of the equation:
-2r = 48
Step 4: Divide both sides of the equation by -2 to solve for r:
-2r / -2 = 48 / -2
This results in:
r = -24
So, the solution to the equation 2r = 48 + 4r is r = -24.
