Question

How do I solve for x correctly?

Answer 1

The answer is:
x = 3

Answer 2

x = 3

Explanation:

`\triangle TFG\sim \triangle TUV... (given)`

`\therefore (FG)/(UV)=(TG)/(TV) ... (csst)`

`\therefore (45)/(63)=(10x+5)/(49)`

`\therefore (5)/(7)=(10x+5)/(49)`

`\therefore 10x+5= (5* 49)/(7)`

`\therefore 10x+5=5* 7`

`\therefore 10x+5=35`

`\therefore 10x=35-5`

`\therefore 10x=30`

`\therefore x=(30)/(10)`

`\therefore x=3`
