Question

Solve the equation -3q + 1.5 = -5 -1.7q

Answer 1

Add 3q to both sides like so: 1.5= -5-1.7q+3q
Add 5 to both sides like so: 5+1.5= -1.7q+3q
Combine like terms: 6.5=1.3q
Divide both sides by 1.3: q=5

Answer 2

-3q+ 1.5= -5 -1.7q
⇒ -3q+ 1.7q= -5 -1.5
⇒ -1.3q= -6.5
⇒ q= -6.5/(-1.3)
⇒ q= 5

Final answer: q=5~
