Answer: 66 degrees
Let's solve your equation step-by-step.
7x+3+x+55=14x−5+x
Step 1: Simplify both sides of the equation.
7x+3+x+55=14x−5+x
7x+3+x+55=14x+−5+x
(7x+x)+(3+55)=(14x+x)+(−5)(Combine Like Terms)
8x+58=15x+−5
8x+58=15x−5
Step 2: Subtract 15x from both sides.
8x+58−15x=15x−5−15x
−7x+58=−5
Step 3: Subtract 58 from both sides.
−7x+58−58=−5−58
−7x=−63
Step 4: Divide both sides by -7.
−7x
−7
