Question

`3(4x-5)-4x+1=-6`

Answer 1

Given that : 3(4x-5)-4x+1 = -6

⇒ 12x-15-4x+1 = -6

⇒ (12x-4x)+(1-15) = -6

⇒ 8x+ −14 = −6

⇒ 8x = -6+14

⇒ 8x = 8

⇒ x = 8÷8

⇒ x = 1

So, value of x is 1

Answer 2

`x=1`

Explanation:

Expand the brackets by multiplying each term in the bracket by the expression outside the bracket:

`3(4x-5)-4x+1=-6`

⇒
`12x-15-4x+1=-6`

Gather like terms and combine:

⇒
`12x-4x+1-15=-6`

⇒
`8x-14=-6`

Add 14 to each side of the equation:

⇒
`8x-14+14=-6+14`

⇒
`8x=8`

Divide both sides by 8:

⇒
`8x /8=8/8`

⇒
`x=1`
