Which is the value of x in the solution to the following system of equations? x-y=-3 x+3y=5

x = -1

Step-by-step explanation:

The system of equations is given as x - y = -3 (1) and

x + 3y = 5 (2)

We have to find the value of x

For which we will eliminate y from these equations.

We multiply equation (1) by 3 and add it to equation (2)

3(x-y) + (x+3y) = -9 + 5

(3x + x) + (3y - 3y) = -4

4x = -4

x = -1

a

step-by-step explanation:

step-by-step explanation:

total income = price of one ticket   *   number of tickets sold

  y                 =     4                                   x

so the equation is y=4x     with x≥0   because number of tickets sold can not be negative

thus the equation is a semi -line with an end point at

(0,0)

passing through :

x=1     y=4(1) = 4   so through (1,4)
