- Solving systems of equations using substitution/elimination
 
Step-by-step explanation:
<u>Step 1: Define Systems</u>
y - 3x = 1
2y - x = 12
<u>Step 2: Rewrite Systems</u>
y - 3x = 1
- Add 3x on both sides:                    y = 3x + 1
 
<u>Step 3: Redefine Systems</u>
y = 3x + 1
2y - x = 12
<u>Step 4: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>:                    2(3x + 1) - x = 12
 - Distribute 2:                         6x + 2 - x = 12
 - Combine like terms:           5x + 2 = 12
 - Isolate <em>x</em> term:                     5x = 10
 - Isolate <em>x</em>:                              x = 2
 
<u>Step 5: Solve for </u><em><u>y</u></em>
- Define equation:                    2y - x = 12
 - Substitute in <em>x</em>:                       2y - 2 = 12
 - Isolate <em>y </em>term:                        2y = 10
 - Isolate <em>y</em>:                                 y = 5
 
 
        
             
        
        
        
Answer:

Step-by-step explanation:
Hello!
The expression is written in the form of 
Let's factor by grouping:

The sum of the factors of -50 should add up to -23.
-25 and 2 work for this.
Expand and factor:
The factored expression is 
 
        
             
        
        
        
The measure of the third angle is 74
        
             
        
        
        
I have no idea what this is asking honestly but i hope you figure it out
