At first, she had  +2y  in the upper and  -5y  in the lower.

She multiplied the upper by  5 .  Then she had  +10y in the upper.

She should multiply the lower by  2 .  Then she'll have  -10y
there.  She'll be able to add the two equations, and the 'y's will
go away.  She'll be left with a single equation with only 'x' in it,
and she can solve that one for the value of 'x'.

HELP PLEASE<br> Use elimination to solve the system of equations<br> 2x + 3y = 9 <br> x + 5y = 8
ikadub [295]

Answer:

y=5/7   x=31/7

Step-by-step explanation:

Make the x values the opposite of each other:

-2(x+5y=8)

-2x-10y=-16

2x+3y=9

Combine like terms and solve for y:

-7y=-5

y=5/7

Plug y in to find x.

x+5(5/7)=8

x+25/7=8

56/7-25/7=x

x=31/7

How do you graph a y-intercept equation? How do you find it in a graph/model/word problem?
ad-work [718]
The y intercept is the initial value, which is graphed on the y axis (or vertical line). In a word problem the y intercept is the original or starting value. In a graph you can find it where the data begins on the vertical axis.
