a/5+15=-3 1/2
No prob, radio.....I gave you points for a "good effort"......it's always easy to make mistakes on here !!!!
a5+15=−3+12
a5=−3+12−15
a=5×(−3+12−15)
a=5×(−3+12−15)⇒a=−87.5
Or if on the right side was-(3+1/2)
a5+15=−(3+12)
a=5×−(3+12)+15
a=5×−(3+12)+15⇒a=−2.5
I think we have.......
a/5 + 15 = -(3 + 1/2) change -(3 + 1/2) to -3.5
a/5 + 15 = -3.5 subtract 15 from both sides
a/5 = -15 -3.5 simplify
a/5 = -18.5 multiply both sides by 5
a = (-18.5) *(5) = -92.5
Ahh. Forgot to combine on each step.
