An unknown number y is 15 more than an unknown number x. The number y is also x less than 8. The equations to find x and y are shown below.

y = x + 15
y = −x + 8

Which of the following statements is a correct step to find x and y? (4 points)


Multiply the equations to eliminate y.

Add the equations to eliminate x. * i think its this one

Write the points where the graphs of the equations intersect the x-axis.

Answer:

add the equations to elimate x

Step-by-step explanation:

I took the test and got a 100%

Add both the equation so that the variable x is eliminated. The solution of the equation y = x + 15 and y = −x + 8 is (-3.5, 11.5).

What is the solution to the equation?

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

An unknown number y is 15 more than an unknown number x.

The number y is also x less than 8.

The equations to find x and y are shown below.

y = x + 15        ...1

y = −x + 8       ...2

Add both the equation so that the variable x is eliminated.

y + y = 15 + 8

2y = 23

y = 11.5

Then the value of x will be

11.5 = -x + 8

x = -11.5 + 8

x = -3.5

The solution of the equation y = x + 15 and y = −x + 8 is (-3.5, 11.5).

The graph is given below.
