What would your first line of work look like when you substitute one equation into the other? Fill in what expression you would substitute for the x.

x-2y=3
4x-8y=12
4( )-8y=12

x-3y=4

step-by-step e

=

x=0.8898305 is the answer to that equation

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.

hi there!

1. define: accuracy

a) how close a measured value is to the actual (true) value.

hope this : )
