Question

Y = 4x
y=19 - x
Solve the system of equations

Answer 1

x = 3.8

y = 15.2

Explanation:

y = 4x

y = 19 - x,

if y = y then,

4x = 19 - x

5x = 19

x = 19/5 = 3.8 now inputting the answer to x into one of the unchanged equations above (y = 4x),

y = 4x = 4*3.8 = 15.2

Double check:

y = 19 - x = 19 - 3.8 = 15.2
