Simply substitute the given number for all the equations.
17) 5b + 1 = 16 where b is -3
5(-3) + 1 = 16
-15 + 1 = 16
-14 ≠ 16
So, the given number is not a solution.
19) 2 = 10 - 4y where y is 2
2 = 10 - 4(2)
2 = 10 - 8
2 = 2
The given number is a solution.
21) -6b + 5 = 1 where b is 0.5
-6(0.5) + 5 = 1
-3 + 5 = 1
2 ≠ 1
The given number is not a solution.

Step-by-step explanation:
Answer:
x=4.
Step-by-step explanation:
Let's solve your equation step-by-step.
5/15=x/ x+8
Step 1: Cross-multiply.
5/15=x/ x+8
5*(x+8)=x*(15)
5x+40=15x
Step 2: Subtract 15x from both sides.
5x+40−15x=15x−15x
−10x+40=0
Step 3: Subtract 40 from both sides.
−10x+40−40=0−40
−10x=−40
Step 4: Divide both sides by -10.
−10x−10=−40−10
Then your answer will be x=4.
