a. add the equations: x=4, and put that x into either to solve for y.
b. multipy the first equation by 3/2,
3x+3/2 y=6 Now subtract the second equation from that.
2x=1
x=1/2 and solve for y.
1) Find the solution to the following system of two linear equations, if it has a solution.
2x-y=3, -x+y=1
2Find the solution to the following system of two linear equations, if it has a solution.
