Solve the system of linear equations by substitution.
x + 4y = 6
x - y = 1

9514 1404 393

  (x, y) = (2, 1)

Step-by-step explanation:

Use the second equation to write an expression for x:

  x = 1 +y

Substitute that into the first equation:

  (1 +y) +4y = 6

  5y = 5 . . . . . . . . subtract 1, collect terms

  y = 1 . . . . . . . divide by 5

  x = 1 +1 = 2 . . . use the expression for x to find x from y

The solution is (x, y) = (2, 1).

the correct answers i think are b. and d.

give me brainliest if it is correct!

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.
