Question

Y=4x-2 y=x+3 what is the an estimated solution

Answer 1

Answer:x=5/3. Y=14/3

Step-by-step explanation:

Y=4x-2 Y-4x=-2---------(1)

Y=x+3 Y-x=3--------------(2)

Subtract (2) from (1)

Y-Y-4x-(-x) =-2-3

0-4x + x=-5

-3x=-5

Divide both sides by -3

-3x/-3=-5/-3

x=5/3

Substitute x=5/3 in Y-x=3

Y-x=3

Y-5/3=3

Collect like terms

Y=3+5/3

Y=(9+5)/3

Y=14/3
