I need help on how to solve the problem and the correct answer :)
lakkis [162]

This is a system of linear equations. First, you can add the two equations together to eliminate the y so that you can solve for x:

-5x + -7x = 0 + -96

-12x = -96

x = 8

Use x to solve for y:

-5 * 8 + 8y = 0

Add 40 to both sides and divide by 8:

y = 5

So, x = 8 and y = 5.

If 5 sips +4 gulps = 1 glass and 13 sips +7 gulps = 2 glasses, how many sips equal a gulp?
nataly862011 [7]

Answer:

3 sips equal a gulp

Step-by-step explanation:

we have

5sips+4gulps=1glass ----> equation A

13sips+7gulps=2glass

Divide by 2 both sides

6.5sips+3.5gulps=1glass ----> equation B

equate equation A and equation B

5sips+4gulps=6.5sips+3.5gulps

Group terms that contain the same variable

4gulps-3.5gulps=6.5sips-5sips

0.5gulps=1.5sips

gulps=(1.5/0.5)sips

gulps=3sips

therefore

3 sips equal a gulp
