Solve the following system of equations by substitution. what is the solution set? y=-2x+3
x-2y=-1

As a point, (1, 1)

Step-by-step explanation:

y = -2x + 3

x - 2y = -1

plug the first equation into the second one

x - 2(-2x + 3) = -1

x + 4x - 6 = -1

5x = 5

x = 1

Now plug x back into the first equation

y = -2 * 1 + 3

y = -2 + 3

y = 1
