Question

Show you work for full credit Use the SUBSITUTION method or ELIMINATION method to solve this system of equations. y = 4x and 8x + y = 18

Answer 1

A. (3/2, 6)

Explanation:

Use the substitution method:

8x + y = 18 and y = 4x

8x +4x = 18

12x = 18

x = 18/12 = 3/2

y = 4x

= 4(3/2)

= 12/2

= 6
