Question

@+@=10
@+$+$=10
@+$-&x @=5
find the value of &​

Answer 1

Answer:

@=10/2=5

so 5+$+$=10

2$=5

$=2.5

5+2.5-&x5=5

7.5-5&=5

-5&=5-7.5=-2.5

&=2.5/-5

&=-0.5

Answer 2

Answer:

32.5

Step-by-step explanation:

@ + @ = 10

@ = 5

@ + $ + $ = 10

5 + $ + $ = 10

$ + $ = 10 - 5

$ + $ = 5

$ = 2.5

@ + $ - & x @ = 5

5 + 2.5 - & x 5 = 5

37.5 - & = 5

- & = 5 - 37.5

- & = - 32.5

& = 32.5
