Answer:
+ 4v - 21
Step-by-step explanation:
Solve for x.
c=8x+60
Flip the equation.
8x+60=c
Add -60 to both sides.
8x+60+−60=c+−60
8x=c−60
Divide both sides by 8.
8x/8=c−60/8
x=1/8c + −15/2
Answer:
b. x= -6 or x=2
Step-by-step explanation:
|2x+ 4| = 8
The absolute value equation has 2 solutions, one positive and one negative
2x+4 = 8 2x+4 = -8
Subtract 4 from each side
2x+4-4 = 8-4 2x+4-4 = -8-4
2x = 4 2x = -12
2x/2 =4/2 2x/2 = -12/2
x =2 x = -6
