Question

Seven times a number is four more than three times the number. What is the number?

Answer 1

Answer:

The number is 1.

Step-by-step explanation:

Let the number be = y

According to the Question,

Seven times a number is four more than three times the number.

$\longrightarrow$ 7y = 3y + 4

$\longrightarrow$ 7y - 3y = 4

$\longrightarrow$ 4y = 4

$\longrightarrow$ y = 4/4

$\longrightarrow$ y = 1

The number = 1

Therefore, the number is 1.

_________________________

★ Verification:

LHS = 7y

$\longrightarrow$ 7(1)

$\longrightarrow$ 7

RHS = (3y + 4)

$\longrightarrow$ 3(1) + 4

$\longrightarrow$ 3 + 4

$\longrightarrow$ 7

LHS = RHS

7 = 7

Hence, verified.

Answer 2

Answer:

Let the number x.

Then 7x=4+3×

7x-3x=4

4x=4

x=4÷4

x=1

So the number is 1
