Step-by-step explanation:
A line that is parallel to a side and intersects the other two siddes divides the sides proportionally.
Set up the proportion
2/x+1 = x/x+6
Multiply means and extremes
2x+12= x^2+ x
Solve to get your answer.
Answer:
x = 2
Step-by-step explanation:
Step 1: Write equation
3x - 5 = 1
Step 2: Solve for <em>x</em>
- Add 5 to both sides: 3x = 6
- Divide both sides by 3: x = 2
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
3(2) - 5 = 1
6 - 5 = 1
1 = 1
2+3 is 5. + 4 is 9. -5 is 4. -2 is 2. -3 is negative 1. 4 times 6 is 24. - 1 is equal to 23
so 23
