Find the solution to the system of equations by using graphing or substitution y=2x-1 and y=x+3
1 answer:
Lets use substitution, since there isn't any graphing method here.
y= x + 3
y = 2x - 1
x + 3 = 2x - 1
-x -x
x - 1 = 3
+1 +1
x = 4
Now solve for y
y = 2(4) - 1
y = 8 - 1
y = 7
We have the solution: (4,7)
