Solve: y=8x+1 and y=6x+3

x = 1 and y = 9

Step-by-step explanation:

y=6x+3

8x+1=6x+3

8x+1+-6x = 6x+3+-6x (Add - 6x to both sides)

2x+1=3

2x+1+-1=3+-1 (Add - 1 to both sides)

2x=2

2x

2

=

2

2

(Divide both sides by 2)

x=1

Step: Substitute 1 for x in y=8x+1:

y=8x+1

y = (8) (1) + 1

y=9 (Simplify both sides of the equation)
