No solution exists = the eqation is false
Proof:
Solve for x:
5/11 (44 x + 33) = 4/3 (15 x + 21)
Expand out terms of the left hand side:
20 x + 15 = 4/3 (15 x + 21)
Expand out terms of the right hand side:
20 x + 15 = 20 x + 28
Subtract 20 x + 15 from both sides:
0 = 13
0 = 13 is trivially false:
Answer: False
