Answer 2

Given:

The equation:-

5x + 45 = 8x + 6

What To Find:

We have to find the value of x.

Solution:

5x + 45 = 8x + 6

Take 5x to RHS,

⇒ 45 = 8x + 6 - 5x

Take 6 to LHS,

⇒ 45 - 6 = 8x - 5x

Solve the both sides,

⇒ 39 = 3x

Take 3 to LHS,

⇒ 39/3 = x

Divide 39 by 3,

⇒ 13 = x

∴ Therefore, the value of x is 13.

Verification:

5x + 45 = 8x + 6

Substitute the value,

⇒ 5 × 13 + 45 = 8 × 13 + 6

Multiply the numbers,

⇒ 65 + 45 = 104 + 6

Solve the both sides,

⇒ 110 = 110

∴ LHS = RHS

∴ Hence, verififed.
