Question

11x -20y=28 3x+4y =36

Answer 1

Answer: X is equal to 8 and Y is equal to 3

Answer 2

Answer:

x = 8

y = 3

Step-by-step explanation:

11x - 20y = 28

3x + 4y = 36

11x - 20y = 28

11x = 20y + 28

x = $\frac{20}{11}$y + $\frac{28}{11}$

3x + 4y = 36

3 ( $\frac{20}{11}$y + $\frac{28}{11}$ ) + 4y = 36

$\frac{104}{11}$y = $\frac{312}{11}$

y = 3

x = $\frac{20}{11}$y + $\frac{28}{11}$

x = $\frac{20}{11}$ ( 3 ) + $\frac{28}{11}$

x = 8
