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

X^3-9x=-1 (divide by 9)

x^3-x=-1/9

But it doesn’t work any further so you have written it wrong
