- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
x - 2y = 12
5x + 3y = -44
<u>Step 2: Rewrite Systems</u>
x - 2y = 12
- [Multiplication Property of Equality] Multiply everything by -5: -5x + 10y = -60
<u>Step 3: Redefine Systems</u>
-5x + 10y = -60
5x + 3y = -44
<u>Step 4: Solve for </u><em><u>y</u></em>
<em>Elimination</em>
- Combine 2 equations: 13y = -104
- [Division Property of Equality] Divide 13 on both sides: y = -8
<u>Step 5: Solve for </u><em><u>x</u></em>
- Define original equation: x - 2y = 12
- Substitute in <em>y</em>: x - 2(-8) = 12
- Multiply: x + 16 = 12
- [Subtraction Property of Equality] Subtract 16 on both sides: x = -4
Answer:

The answer to this is quite simple my friend.
So if you were 9, purely turning on November 9th of 2015 at a undisclosed time, you would've been born in November of 2006. Currently, now of October 16, 2021, you would be:
Add:
4 + 10 + 1 = 15
So you would be 15 years old.
Hope this helps, currently it's 10/17/2021 for me and 1:56 am (EST).
Have a nice morning, night, dusk etc.

Answer:
x = 4
Step-by-step explanation:
divide both sides by 5- 2x + 5 = 13 subtract 5 from both sides
- 2x = 8 divide both sides by 2
- x = 4
