Determine if (1, 3) is a solution to the given system of linear equations. 5x+y=8 x+2y=5 (1 point) No, because substituting the given ordered pair yields two true expressions.

No, because substituting the given ordered pair doesn't yields two true expressions.

Yes, because substituting the given ordered pair doesn't yield two true expressions.

Yes, because substituting the given ordered pair yields two true expressions.

5x+y=8 equation 1

x+2y=5 equation 2

Subsitute (1,3) in bothe equations if the right side is equal to.the left side of the equation then (1,3) is a solution

5(1)+3=8

1+2(3)=7

7 isn't equal to 5 so 1,3 is NOT a solution for this system of equations

Explanation:

The commutative property of addition is A+B = B+A. We can add two numbers in any order. For example: 2+3 = 3+2 since both sides result in 5.

The idea applies to fractions as well. In choice D, the fractions 3/5 and 2/3 swap places so that we can group the 1/3 and 2/3. From there, the 1/3 and 2/3 combine to 1 and that's how we end up with the mixed number 1 & 3/5.
