Solve the system of equations using the substitution method.

y = 7x - 16.
y = 2(2x - 5)
What is the solution?
Intro
8 of 10

Answer 1

y = 7x - 16:

Slope = 14.000/2.000 = 7.000

x-intercept = 16/7 = 2.28571

y-intercept = -16/1 = -16.00000

y = 2(2x - 5)=

Slope = 8.000/2.000 = 4.000

x-intercept = 10/4 = 5/2 = 2.50000

y-intercept = -10/1 = -10.00000
