Alright, Since my previous questions have not been answered, here's 50p to whoever solves this

Two times x is 16 more than y. The sum of x and two times y is 18.
find the value of y.

Answer 1

Explanation:

We can make 2 equations as follows:

2x = y + 16 and x + 2y = 18

x + 2y = 18 is the same as x = 18 - 2y. Hence, 2(18 - 2y) = 2x = y + 16.

2(18 - 2y) = y + 16

36 - 4y = y + 16

5y = 20

y = 4.
