Answer:
The number is 6.
Step-by-step explanation:
Firstly, we can make the unknown value as x which is much easier to find. Next, by reading the question, we can form an expression in terms of x :
9 × x + 8 = 50 + 2 × x
9x + 8 = 50 + 2x
Now, you can find the value of x by making x as a subject :
9x + 8 = 50 + 2x
9x - 2x = 50 - 8
7x = 42
x = 42/7
= 6
