10(x−2)+15=8x+7
Simplify
10(x−2)+15=8x+7
(10)(x)+(10)(−2)+15=8x+7(Distribute)
10x+−20+15=8x+7
(10x)+(−20+15)=8x+7(Combine Like Terms)
10x+−5=8x+7
10x−5=8x+7
Subtract 8x from both sides.
10x−5−8x=8x+7−8x
2x−5=7
Add 5 to both sides.
2x−5+5=7+5
2x=12
Divide both sides by 2.
2x/2 = 12/2
x=6
Answer:

Step-by-step explanation:
Answer:
3z+3x=2
Step-by-step explanation:
3z+8=12+3x-2
collecting like terms
3z-3x=12-2-8
3z-3x=2
3z=2+3x
divide through by three
z= ⅔+x
