Answer:
10/7
Explanation:
Step 1: Subtract 12x from both sides.
−2x+5−12x=12x−15−12x
−14x+5=−15
Step 2: Subtract 5 from both sides.
−14x+5−5=−15−5
−14x=−20
Step 3: Divide both sides by -14.
−14x/14=−20/14
x=10/7
You get 10 over 7 because you simplify 20 over 14 by dividing them by 2 which would give you 10/7.
