5x + 3(x – 5) = 6x + 2x – 15
Part A: Solve the equation and write the number of solutions. Show all the steps. (6 points)
Part B: Name one property you used to solve this equation. (4 points)
Hi there
5x+3(x-5)=6x+2x-15
Simplify both sides of the equation
5x+3(x-5)=6x+2x-15
Distribute
5x+3x-15=6x+2x-15
Combine like terms
(5x+3x)-15= (6x+2x)-15
8x-15=8x-15
Subtract 8x from both sides
8x-15-8x=8x-15-8x
-15=-15
Add 15 to both sides
-15+15=-15+15
0=0
All real numbers are solutions
To solve this equation I used " The distributive property"
I hope that's help !
Good night !

B. plane B only
C. both plane A and B
D. neither plane A or B
Answer: C. Both plane A and B.
Step-by-step explanation: We very well know that if two planes intersect, then their intersection is a straight line.
We are given two planes- plane A and plane B, which intersect at a line S. Now, since 's' is the intersection of these two planes, so all the points on the line 's' will also be on the planes A and B.
It is given that 'V' is a point on the line 's', so 'V' will also lie on plane A as well as on plane B. Please see the attached figure.
Thus, the correct option is C. both plane A and B.
