hope this helps!
Answer:
(3, 1)
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define systems</u>
3x + y = 10
y = x - 2
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute: 3x + (x - 2) = 10
- Combine like terms: 4x - 2 = 10
- Isolate <em>x </em>term: 4x = 12
- Isolate <em>x</em>: x = 3
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation: y = x - 2
- Substitute in <em>x</em>: y = 3 - 2
- Subtract: y = 1
And we have our answer!

Anyway the distance is 1.
I give you the graphic of this function
Answer: No solution
Step-by-step explanation:
x + 2x +7 = 3x - 7
3x + 7 = 3x - 7
3x + 7 - 7= 3x - 7 - 7
3x = 3x - 14
3x - 3x = 3x - 14 - 3x
0 = -14
The sides are not equal so there is no soulution.
