1)The sum of the angles A B C is 180 degrees (a line). Reason: All triangles have this property.
2) 2 right angles are supplementary (add up to a line). Reason: If we have a normal to a line, the two resulting angles are right and they add up to a line.
3) A is supplementary to the sum of B and C. Reason: 1)
4) A right angle is supplementary to A. Reason: 2)
5) The sum of B and C is a right angle. Hence, B and C are complimentary. Reason: This results from 3 and 4 and congruency of angles.

3(5y+2)-y=2(y-3)<br><br>please help. I'm desperate ​
Keith_Richards [23]

Answer:

y = -1

Step-by-step explanation:

((3 • (5y + 2)) -  y) -  2 • (y - 3)  = 0  

Step  2  :

Equation at the end of step  2  :

 (3 • (5y + 2) -  y) -  2 • (y - 3)  = 0  

Step  3  :

Step  4  :

Pulling out like terms :

4.1     Pull out like factors :

  12y + 12  =   12 • (y + 1)  

Equation at the end of step  4  :

 12 • (y + 1)  = 0  

Step  5  :

Equations which are never true :

5.1      Solve :    12   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

5.2      Solve  :    y+1 = 0  

Subtract  1  from both sides of the equation :  

                     y = -1

One solution was found :

                  y = -1

What is a solution for both equations y=x+3 and -2x+y=1
Soloha48 [4]

Answer:

(2, 5)

Step-by-step explanation:

Given the 2 equations

y = x + 3 → (1)

- 2x + y = 1 → (2)

Substitute y = x + 3 into (2)

- 2x + x + 3 = 1

- x + 3 = 1 ( subtract 3 from both sides )

- x = - 2 ( multiply both sides by - 1 )

x = 2

Substitute x = 2 into (1) for corresponding value of y

y = 2 + 3 = 5

Solution is (2, 5)
