Solve the system: x-2y=1y=x+2substitution method provide explanation,

x=-5, y=-3

Step-by-step explanation:

Given the system of two equations

Substitute the second equation into the first one:

Then

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .

the answer is 0.071

good luck! : d
