Answer:
y=-61/2=-30 1/2=-30.5
Explanation:
Add −15 and 7 to get −8.
−8+17=2y+70
Add −8 and 17 to get 9.
9=2y+70
Swap sides so that all variable terms are on the left hand side.
2y+70=9
Subtract 70 from both sides.
2y=9−70
Subtract 70 from 9 to get −61.
2y=−61
Divide both sides by 2.
y=-61/2
Fraction
−61/2 =−30.5 can be rewritten as − 61/2=−30.5 by extracting the negative sign.
y=-61/2=-30 1/2=-30.5
