Question

3(2x-1)+2(1-5x)=9+x and check the answer

Answer 1

Given

• 3(2x - 1) + 2(1 - 5x) = 9 + x

⠀

To find

• Value of x.

⠀

Solution

• Firstly, we will solve the left hand side then find the value of x.

⠀

$\tt\longrightarrow{6x - 3 + 2 - 10x = 9 + x}$

⠀

$\tt\longrightarrow{6x - 10x - 3 + 2 = 9 + x}$

⠀

$\tt\longrightarrow{-4x - 1 = 9 + x}$

⠀

$\tt\longrightarrow{-4x - x = 9 + 1}$

⠀

$\tt\longrightarrow{-5x = 10}$

⠀

$\tt\longrightarrow{x = \dfrac{10}{-5}}$

⠀

$\bf\longrightarrow{x = -2}$

⠀

⠀❍ Hence,

• The Value of x is -2.

⠀

★ By putting the value of x we will verify our answer.

⠀

$\large{\boxed{\boxed{\sf{Let's\: verify\: it !!}}}}$

⠀

$\tt\longmapsto{3[2(-2) - 1] + 2[1 - 5(-2)] = 9 + (-2)}$

⠀

$\tt\longmapsto{3[-4 - 1] + 2[1 + 10] = 9 - 2}$

⠀

$\tt\longmapsto{3[-5] + 2[11] = 7}$

⠀

$\tt\longmapsto{-15 + 22 = 7}$

⠀

$\bf\longmapsto{7 = 7}$

⠀

$\tt\longmapsto{\boxed{\red{L.H.S = R.H.S}}}$

⠀

⠀❍ Hence Verified !!
