Which is the solution for the system of equations?

y = 2x – 3
y = –x

(1, –1)

no solution

( –1,1)

(–1, –1)

I think the answer is: (1,-1)

Step-by-step explanation:

If you plug in y=-x into the equation y=2x-3 (-x=2x-3) and graph it you will find the intercept of the two lines is (1, -1)

The price of the breakfast was $9.

Step-by-step explanation:

Let x be the price of the breakfast.

We know that 20 percent of x is 1.80

Let's write this as a mathematical equation

0.2 x = 1.8

Let's divide both sides by 0.2 to isolate the x

x = 1.8 / 0.2

= 9

The price of the breakfast was $9.

hope this helps !
