Solve the equation for the r variable. Please show your steps
0.25r - 0.25 + 0.5r = 0.5 + r
To solve the equation for the r variable, we can start by combining like terms.
0.25r + 0.5r - r = 0.5 + 0.25
Simplifying, we have:
0.75r - r = 0.75
The next step is to combine the r terms:
-0.25r = 0.75
To isolate the r variable, divide both sides of the equation by -0.25:
r = 0.75 / -0.25
Finally, we simplify the right side of the equation:
r = -3
Step 1: Distribute the terms on the left side of the equation:
0.25r - 0.25 + 0.5r = 0.5 + r
Simplify the left side by combining like terms:
0.75r - 0.25 = 0.5 + r
Step 2: Simplify the equation further by moving all terms with "r" to one side and all constant terms to the other side:
0.75r - r = 0.5 + 0.25
Combine like terms:
-0.25r = 0.75
Step 3: To isolate the variable "r", divide both sides of the equation by -0.25:
-0.25r / -0.25 = 0.75 / -0.25
This simplifies to:
r = -3
