How do you solve #17=7+8y#?

Answer 1

Kennedy Adams

#y=5/4#

Resolve:

#17=7+8y#

Change positions.

#8y+7=17#

Subtract #7# from both sides.

#8y+color(red)cancel(color(black)(7))-color(red)cancel(color(black)(7))=17-7#

Reduce complexity.

#8y=10#

Divide both sides by #8#.

#(color(red)cancel(color(black)(8))^1y)/color(red)cancel(color(black)(8))^1=10/8#

Make it simple.

#y=10/8#

Reduce by dividing the numerator and denominator by #2#.

#y=(10-:2)/(8-:2)#

Make it simple.

#y=5/4#

To solve the equation 17 = 7 + 8y:

Subtract 7 from both sides: 17 - 7 = 7 + 8y - 7 10 = 8y
Divide both sides by 8: 10 / 8 = 8y / 8 5/4 = y

So, the solution to the equation is y = 5/4 or y = 1.25.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
