Question

Amina thinks of a number and subtracts 5 upon 2 from it. she multiplies the result by 8. the result now obtained is 3 times the same number she thought of. what is the number ?​

Answer 1

Answer:

5-2=3 , 3×8=24,= 24×3m

Answer 2

Answer:

Let number she is thinking be x,

then,

she subtracted 5/2 from it,

x-5/2

now multiply 8 to it

x-5/2×8

Now, number she get is 3 times the same number she was thinking first means x, so,

x-5/2×8 = 3x

2x-5/2×8 = 3x

4(2x-5) = 3x

8x-20 = 3x

5x=20

x=4
