Answer 2

Given:

4x + 7 = 15

What To Do:

Solve the equation to find the value of x and verify it.

How To Do:

To find the value of x,

• First, rearrange the terms.
• Next, take the variable and numbers to different side.
• Then, solve the equation.

To verify the answer,

• First, substitute the value of the variable.
• Then, solve the equation.

Solution:

4x + 7 = 15

Take 7 to LHS,

⇒ 4x = 15 - 7

Subtract 7 from 15,

⇒ 4x = 8

Take 4 to RHS,

⇒ x = 8/4

Divide it,

⇒ x = 2

To Verify:

4x + 7 = 15

Substitute the values,

⇒ 4 × 2 + 7 = 15

Multiply 4 by 2,

⇒ 8 + 7 = 15

Add 8 and 7,

⇒ 15 = 15

∴ RHS = LHS

∴ Hence, verified.
