What is the x-value of the solution to the system of equations? 5x + 4y =8
2x- 3y = 17
O -3
O -2
O 4
O5

The solution to the system of equations is:

Step-by-step explanation:

Given the system of equations

solving the system of equations

solve for y

Divide both sides by -23

Divide both sides by 10

Thus, the solution to the system of equations is:

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

make sure you have version 2.50

try looking in the very back of the book : )
