Show that (2, 1) is a solution of the system of equations.
x + 3y = 5,
y = –x + 3
Substitute (2, 1) into x + 3y = 5 to get .
Simplify the equation to get
Substitute (2, 1) into y = –x + 3 to get
Simplify the equation to get .

Step-by-step explanation:

Put the first value of the ordered pair where x is in the equation. Put the second value of the ordered pair where y is in the equation. This gives you the expressions that go in the "Substitute (2, 1) into ..." blanks.

Perform the indicated arithmetic to simplify the expression.

You will get answers that look like ...

the solution is h=10 because you add 9 to each side of the equation.

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
