Question

Subtracting three from two times a number is three more than four times that number. What is the number?

Answer 1

Let the no. be X
2x-3 = 3+ 4x
2x = -6
X = -3

Answer 2

Answer:

x = -3

Step-by-step explanation:

Let the Number be x

Let 2 times the Number be 2x

2x - 3 = 3 + 4x

-3 -3 = 4x - 2x

-6 = 2x

x = -6/2

x = -3

Proof:

(-3*2)-3 = 3 + (4* -3)

-9 = -9

Clearly, LHS = RHS

Hence Proved
