Question

Who knows thisssss ???

Answer 1

(3,2)

Explanation:

3x+5(5x-13)=19

3x+25x-65=19

28x-65=19

+65 +65

28x=84

84/28=3

x=3

y=5(3)-13

y=15-13

y=2

Answer 2

(3, 2)

Explanation:

y = 5x - 13

3x + 5y = 19

~Substitute since we know what "y" equals

3x + 5(5x - 13) = 19

~Simplify

3x + 25x - 65 = 19

28x - 65 = 19

~Solve for x

28x = 84

28x/28 = 84/28

x = 3

~Solve for y using what we got for x

y = 5(3) - 13

y = 15 - 13

y = 2

Best of Luck!
