Question

Simplify the expression: 2(3x – 5) + 4x - 7

Answer 1

10x -17

Explanation:

`2(3x - 5) + 4x - 7\\\\\mathrm{Expand}\:2\left(3x-5\right):\quad 6x-10\\\\=6x-10+4x-7\\\\\mathrm{Simplify}\:6x-10+4x-7:\\\\\quad 10x-17`

Answer 2

`\huge{ \fbox{ \sf{10x - 17}}}`

Explanation:

`\sf{ \: 2(3x - 5) + 4x - 7}`

Distribute 2 through the parentheses

`\mapsto{ \sf{6x - 10 + 4x - 7}}`

Add the like terms : 6x and 4x

Like terms are those which have the same base.

`\mapsto{ \sf{10x - 10 - 7}}`

`\underline{ \text{Remember!}} :` The negative integers are always but added but posses the negative ( - ) sign.

`\mapsto{ \sf{10x - 17}}`

Hope I helped!
