Answer:
x = 41/3
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
7(1x - 3) = 4(x + 5)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Simplify: 7(x - 3) = 4(x + 5)
- Distribute: 7x - 21 = 4x + 20
- Subtract 4x on both sides: 3x - 21 = 20
- Add 21 on both sides: 3x = 41
- Divide 3 on both sides: x = 41/3
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: 7(1(41/3) - 3) = 4(41/3 + 5)
- Multiply: 7(41/3 - 3) = 4(41/3 + 5)
- Subtract/Add: 7(32/3) = 4(56/3)
- Multiply: 224/3 = 224/3
Here, we see that 224/3 is indeed equivalent to 224/3. ∴ x = 41/3 is a solution to the equation.
And we have our final answer!

Answer:
The conclusion is "Plane R and Plane S form a line if they intersect."
Step-by-step explanation:
Consider the provided statements.
1) If two planes intersect, their intersection is a line.
2) Plane Rand plane S intersect.
- If two points lie in a plane, then the line joining them lies in that plane.
- If two planes intersect, then their intersection is a line.
For better understanding refer the figure:
There are two planes R and S, which intersect at the line l.
Since the given two planes intersect, the using the above fact we can say that their intersection is a line.
Thus, the conclusion is "Plane R and Plane S form a line if they intersect."
