Suppose Megan has enough money to buy 1 hat and 2 shirts for $21 and then another 2 hats and 1 shirt for $18.  In total, she has bought 3 hats and 3 shirts for $39.  But she has enough for only 1 hat and 1 shirt and so Megan has 39 ÷ 3 = $13.

X + y = 5 ; x - y =3 solve using linear combination
Bas_tet [7]

Answer:

x = 4

y = 1

Step-by-step explanation:

use one equation to solve for one variable.

y = 5 - x

Now plug the value of y in the other equation

x - (5-x) = 3

x+x= 3+5

2x=8

x=4

Now use the value of x to find the value of y on the first equation

y = 5 - x

y = 5 - 4

y = 1
