Question

Solve the system. Estimate the solution first. Enter whole numbers for the estimated solution and

improper fractions in simplest form for the algebraic solution.
6x + y = 4
x - 4y = 19
The estimated solution is
The algebraic solution is

Answer 1

x= 4y+19
6(4y+19)+y=4
24y+114+y=4
24y=110
y= 4.583333
y=5

x-4(4.58333)=19
x-18.3332=19
x=37.3332
x=37
