Solve the following system of equations using the substitution method x= 4y - 1
x+ 2y = 11

x = 7,   y = 2

Step-by-step explanation:

To use the substitution method, we can that the value of "x" (4y - 1) and plug that into the second equation to find "y":

x + 2y = 11

(4y - 1) + 2y = 11

6y - 1 = 11

6y = 12

y = 2

Then we can plug the value of "y" into the first equation to get "x":

x = 4y - 1

x = 4(2) - 1

x = 8 - 1

x = 7
