Question

15 - 4x =7 , x = 2 , -2 , 1​

Answer 1

Answer:

x= 2

Step-by-step explanation:

put the value of x=2

15-4 (2)=7

15-8=7

7=7

Answer 2

$\large{\underline{\underline{\red{\bf{Solution}}}}}$

⠀

Given Equation

• 15 - 4x = 7

⠀

To find

• Value of x.

⠀

Solving the equation for the value of x.

⠀

→ 15 - 4x = 7

→ - 4x = 7 - 15

→ - 4x = - 8

⠀

[Cancelling the negative sign both the sides]

→ 4x = 8

→ x = 8/4

→ x = 2

⠀

Hence,

• Value of x is 2.

⠀

For checking our answer, we have to verify the value of x. For verifying, we have to put the value of x in the equation and prove the L.H.S = R.H.S

⠀

Verification

→ 15 - 4(2) = 7

→ 15 - 8 = 7

→ 7 = 7

→ L.HS. = R.H.S

⠀

Hence proved !!
