Question

Use the Substitution Method to solve the following system of equations.
2x + y = 3
-3x + 4y = 1

Answer 1

substitution
solve the first equation for y, get
\[y=3-2x\] and substitute that for y in the second equation, get
\[-3x+4(3-2x)=1\] solve that one

Answer 2

so could the answer be 1,1?

Answer 3

or would it be 1, -1

Answer 4

x = 1, y = 1
