An unknown number y is 10 more than an unknown number x. the number y is also x less than 3. the equations to find x and y are shown below. y = x + 10 y = −x + 3 which of the following statements is a correct step to find x and y? add the equations to eliminate x. multiply the equations to eliminate y. write the points where the graphs of the equations intersect the x-axis. write the points where the graphs of the equations intersect the y-axis.

The correct option is A.

Step-by-step explanation:

Let two unknown numbers are x and y.

An unknown number y is 10 more than an unknown number x.

           ... (1)

The number y is also x less than 3.

          .... (2)

We can use elimination method to solve the system of inequality.

In equation (1) and (2), the coefficient of x is same with opposite sign.

Add the equations to eliminate x.

Divide both sides by 2.

Substitute y=6.5 in equation (1).

The value of xis -3.5 and value of y is 6.5.

Therefore the correct option is A.
