Step-by-step explanation:
the angles are supplementary to the angle in the diagram is Angle BCF
Let's say you have the equation
5x + 3y = 11
You are asked to test the ordered pair (1, 2) to see if it is a solution of the equation. A solution of the equation will make the equation a true statement. The ordered pair (1, 2) has 1 as its x-coordinate and 2 as its y-coordinate.
Substitute 1 for x and 2 for y in the equation. Then work it out to see if it is a true statement.
5x + 3y = 11
5(1) + 3(2) = 11
5 + 6 = 11
11 = 11
Since 11 = 11 is a true statement, the ordered pair (1, 3) is a solution of the equation.
Answer: 2z + 6
Step-by-step explanation: Distribute the 2 to z and 3.
-4x +4 = -3x + 31
4 - 31 = -3x + 4x
-27 = x
