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?
a) multiply the equations to eliminate y.
b)add the equations to eliminate x.
c) write the points where the graphs of the equations intersect the x-axis.
d) write the points where the graphs of the equations intersect the y-axis.

b)Add the equations to eliminate x.

Step-by-step explanation:

y= x+20

y= - x+2

Result of the addition: (-x cancels x)

2y = 22

y =11

11=x +20            -9 = x

11=9+2

11 = -9 +20

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17
