Solve the system. estimate the solution first. enter whole numbers for the estimated solution and improper fractions in simplest form for the algebraic solution.

braceleftze 3x + y = 3
5x − y = 15

the estimated solution is (, ).

the algebraic solution is

The estimated solution is (x, y) = (2, -4)

The algebraic solution is (x, y) =

Solution:

Given system of equations are:

3x + y = 3 ---- eqn 1

5x - y = 15 ------- eqn 2

Let us solve the above system of equations

Add eqn 1 and eqn 2

3x + y + 5x - y = 3 + 15

8x + 0 = 18

8x = 18

Substitute the value of "x" in eqn 1

The estimated solution is given as:

Enter whole numbers for the estimated solution

Thus estimated solution is (x, y) = (2, -4)

The algebraic solution is given as:

Enter improper fractions in simplest form for the algebraic solution

In an improper fraction, the numerator is always greater than or equal to the denominator

Thus the solution is (x, y) =
