An unknown number b is 10 more than an unknown number k. The number b is also k less than 8. The equations to find k and b are shown below:

b = k + 10
b = −k + 8

Which is a correct step to find k and b?

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.
Add the equations to eliminate k.
Multiply the equations to eliminate b.
