Question

Y= 5x+9, y=8x-6 find x and y

Answer 1

x= 5, y= 34

Explanation:

y= 5x +9 -----(1)

y= 8x -6 -----(2)

Substitute (1) into (2):

5x +9= 8x -6

Bring x terms to one side, constants to the other:

8x -5x= 9 +6

3x= 15

Divide both sides by 3:

x= 15 ÷3

x= 5

Substitute x= 5 into (1):

y= 5(5) +9

y= 25 +9

y= 34
