Question

If 2x - 4 = 4 then find 5x

Answer 1

Question:-

If 2x - 4 = 4 then find 5x.

Answer:-

• The value of 5x is 20.

To find:-

• Value of 5x

Solution:-

$\implies \: 2x - 4 = 4 \\ \\ \implies \:2x = 4 + 4 \\ \\ \implies \:x = \frac{ \cancel8}{\cancel2} \\ \\ \implies \:x = 4$

• The value of x is 4.

According to question:-

$\implies \: 5x = 5 \times 4 \\ \\ \implies \:5x = 20$

Hence,

The value of 5x is 20.

Answer 2

Given

• 2x - 4 = 4

To find

• Value of 5x.

Solution

[For solving this question, we have to calculate the value of x]

→ 2x - 4 = 4

→ 2x = 4 + 4

→ 2x = 8

→ x = 8/2

→ x = 4

[Now, multiplying the value of x with 5]

• 5x = 5 × 4
• 5x = 20

Hence, the value of 5x is 20.
