- Coordinates (x, y)
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
6x - 5y = 15
x = y + 3
<u>Step 2: Solve for </u><em><u>y</u></em>
<em>Substitution</em>
- Substitute in <em>x</em>:                                                                                                  6(y + 3) - 5y = 15
- Distribute 6:                                                                                                    6y + 18 - 5y = 15
- Combine like terms:                                                                                        y + 18 = 15
- [Subtraction Property of Equality] Subtract 18 on both sides:                     y = -3
<u>Step 3: Solve for </u><em><u>x</u></em>
- Define original equation:                                                                               x = y + 3
- Substitute in <em>y</em>:                                                                                                   x = -3 + 3
- Add:                                                                                                                   x = 0
 
        
             
        
        
        
Answer:
23
Step-by-step explanation:
1)  (10*0.5)+(-6*-3) 
2) (5)+(18) (The 18 isn't negative because of the rule that states "A negative and a negative will become positive"
3) 5+18=23
