Step-by-step explanation:
1/5(10x−15)=1/4(12x−8)
1/5(10x−15)=1/4(12x−8)
Simplify:
(1/5)(10x)+(15)(−15)=(1/4)(12x)+(1/4)(−8)(Distribute)
2x+−3=3x+−2
2x−3=3x−2
Subtract 3x from both sides.
2x−3−3x=3x−2−3x
−x−3=−2
Add 3 to both sides.
−x−3+3=−2+3
−x=1
Divide both sides by -1.
−x/−1 = 1/−1
x=−1
Common factor because its used more than once so its common
