How many solutions does this system have?

no solution

Step-by-step explanation:

Solve by substitution

Divide each term by 2 and simplify.

Replace all occurrences of y with the solution found by solving the last equation for y. In this case, the value substituted is 5x+1.

Solve for x in the second equation.

Since −1≠3, there are no solutions.

42%

step-by-step explanation:

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
