A soccer team ordered 12 jerseys and 12 pairs of shorts, for a total of $156. Later, they had to order 4 more jerseys and 6 more

lyudmila [28]

Answer:

Jersey cost $8 and pair of shorts $5

Step-by-step explanation:

There are several ways to solve this, but I will find the solution using the system of equations.

Let's mark price of jersey with x, and price of pair of shorts with y. That means:

12x + 12y = 156

4x + 6y = 62

Now, we can multiply the second equation with -2 to cancel out y:

12x + 12y = 156

-8x - 12y = -124

That only leaves us with:

12x - 8x = 156 - 124

4x = 32

x = $8

Now we plug the value for x into any equation to find y:

4x + 6y = 62

32 + 6y = 62

6y = 30

y = $5

Will the following two equations have a solution? Explain. y = 3x + 5 y = 3x - 7

r-ruslan [8.4K]

Answer:

There is no solution because the slopes of the two lines are the same.

Step-by-step explanation:

3x + 5 = 3x - 7

-3x - 3x Subtract 3x from both sides

5 ≠ - 7 No solution
