Han is solving an equation. He took steps that are acceptable but ended up with equations that are clearly not true. 5x+6=7x+5-2x5x+6=7x+5−2x original equation

5x+6=7x-2x+55x+6=7x−2x+5 apply the commutative property

5x+6=5x+55x+6=5x+5 combine like terms

6=56=5 subtract 5x from each side

What can Han conclude as a result of these acceptable steps?

no solution

Step-by-step explanation:

5x+6=7x+5-2x original equation

5x+6=7x-2x+5 apply the commutative property

5x+6=5x+5 combine like terms

6=5subtract 5x from each side

Since this is never true, there is no solution

if x = 1, then the answer is 3.5
