PLEASE HELP What steps do you use to solve a system of two equations using substitution? For example:
3b-45c=120
b-3c=10

solve one equation for a vriable then substitute that varibale into the other equation.

Step-by-step explanation:

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
