-85 - 8x =2x + 115 anyone know how to do this??
2 answers:
-85 - 8x = 2x + 115
-85 + 85 - 8x = 2x + 115 + 85
-8x = 2x + 200
-8x - 2x = 2x - 2x + 200
-10x = 200
-10x/-10 = 200/-10
X = -20
Answer: x= -20
Step-by-step explanation:
Add 85 85 to both sides.
-8x=2x+115+85−8x=2x+115+85
Simplify 2x+115+852x+115+85 to 2x+2002x+200.
-8x=2x+200−8x=2x+200
Subtract 2x2x from both sides.
-8x-2x=200−8x−2x=200
Simplify -8x-2x−8x−2x to -10x−10x.
-10x=200−10x=200
Divide both sides by -10−10.
x=-\frac{200}{10}x=−
10
200
Simplify \frac{200}{10}
10
200
to 20 20.
x= - 20
