Answer :
Simplifying
R + 74 = r + -74
Reorder the terms:
74 + R = r + -74
Reorder the terms:
74 + R = -74 + r
Solving
74 + R = -74 + r
Solving for variable 'R'.
Move all terms containing R to the left, all other terms to the right.
Add '-74' to each side of the equation.
74 + -74 + R = -74 + -74 + r
Combine like terms: 74 + -74 = 0
0 + R = -74 + -74 + r
R = -74 + -74 + r
Combine like terms: -74 + -74 = -148
R = -148 + r
Simplifying
R = -148 + r
R + 74 = r + -74
Reorder the terms:
74 + R = r + -74
Reorder the terms:
74 + R = -74 + r
Solving
74 + R = -74 + r
Solving for variable 'R'.
Move all terms containing R to the left, all other terms to the right.
Add '-74' to each side of the equation.
74 + -74 + R = -74 + -74 + r
Combine like terms: 74 + -74 = 0
0 + R = -74 + -74 + r
R = -74 + -74 + r
Combine like terms: -74 + -74 = -148
R = -148 + r
Simplifying
R = -148 + r
Step-by-step explanation:
R+74=R-74
subtract 74 from both sides
R+74-74=R-74-74
R=R-148
Subtract R from both sides
R-R=R-148-R
0=-148
The input is contradiction, it has no solution
