What is the solution to the system of equations?
Use any method.
{3x+y=3
{2x+y=7
Enter your answer in the boxes. Parentheses are already provided.

x=-4, y=15

Step-by-step explanation:

3x+y=3

2x+y=7

Multiply top by -1

-3x-y=-3

2x+y=7

Add equations together

-x=4

x=-4

Plug x=-4 into any equation

3(-4)+y=3

-12+y=3

y=15

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
