Question

An unknown number y is 20 more than an unknown number x. The number y is also x less than 2. The equations to find x and y are shown below: y = x + 20 y = −x + 2 Which is a correct step to find x and y? Multiply the equations to eliminate y. Add the equations to eliminate x. 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. Question

Answer 1

The graph is given below. Then the intersection point will be (-9, 11).

What is the linear system?

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

An unknown number y is 20 more than an unknown number x.

The number y is also x less than 2.

The equations to find x and y are shown below:

y = x + 20 ...1

y = −x + 2 ...2

Add both equations, then we have

2y = 22

 y = 11

Then put the value of y in equation 1, then we get

11 = x + 20

x = 11 - 20

x = -9

Then the intersection point will be (-9, 11)
