Answer:

x = 11.75

y = 11.5

Step-by-step explanation:

By Elimination Method:

   7x - 3y = 48    ---- (1)

-

<u>    2x + y = 35   ----</u>-   (2)

Multiply equation (1) by 2 and equation (2) by 7

   14x - 6y = 96

-

<u>    14x + 7y = 245      </u>

<u>      0   -13y = -149</u>

-13y = -149

y = -149/-13

y = 11.5

From equation (2); replace y with 12

2x + y = 35

2x + 11.5 = 35

2x = 35 - 11.5

2x = 23.5

x = 11.75
