Question

5x−2+x=9+3x+10 what is x?

Answer 1

Answer: X = 17

Step-by-step explanation: First combine like terms on both sides so the 5x + x on the left side for a total of 6x and the 9 + 10 on the right side for a total of 19. Then get your variables and numbers all to one side each so you would add 2 from the left to the right and cancel out and then subtract 3x from the right to the left and cancel out. Finally you would divide 21 by 3.

5x-2+x=9+3x+10

6x-2=19+3x

+2 -3x

3x=21

/3. /3

x=7

Answer 2

  `\tt x=7`

Explanation:

`\tt 5x-2+x=9+3x+10`

Combine like terms:-

`\tt 5x+x-2=9+3x+10`

`\tt \:5x+x=\bf 6x`

`\tt 6x-2=9+3x+10`

Add numbers:-

`\tt 9+10=\bf 19`

`\tt 6x-2=3x+19`

Add 2 to both sides:-

`\tt 6x-2+2=3x+19+2`

`\tt 6x=3x+21`

Subtract 3x from both sides:-

`\tt 6x-3=3x+21-3`

`\tt 3x=21`

Divide both sides by 3:-

`\tt \cfrac{3x}{3}=\cfrac{21}{3}`

`\tt x=7`
