Solve the system, using substitution. x = 4y, 2x+3y = 44.

X=4y; 2x+3y=44

Solve x=4y for x:

Substitute (4y) for x in 2x+3y=44

2x+3y=44

24y+3y=44

11y=44 (Simplify)

11y/11=44/11 (Divide)

y=4

Substitute (4) for y in x=4y

x=4y

x = (4) (4)

x=16 (Simplify)

x=16 and y=4

2*4y+3y=44

8y+3y=44

11y=44

=> y=4

=> x=4*4=16
