Answer:
The answer is C!
Step-by-step explanation:
You just have to count the all the x's that are at 50 and after!
I hope this helps you!
A.
5(5+x)=6(6+4)
Solving for x:
5(5+x)=6(10)
5(5+x)=60
5(5+x)/5=60/5
5+x=12
5+x-5=12-5
x=7
b.
4(4+x)=3(3+5)
Solving for x:
4(4+x)=3(8)
4(4+x)=24
4(4+x)/4=24/4
4+x=6
4+x-4=6-4
x=2
Hello from MrBillDoesMath!
Answer:
x = 0 or x = 3
Discussion:
Solve
x^2 -2x = x =>
x^2 - 2x - x = 0 => (subtract x from both sides)
x^2 - 3x = 0 =>
x(x-3) = 0 => (factor "x" from each term)
x = 0 or x = 3
