Question

Solve equation.

-3x + 1 + 10x = x + 4

Answer: x=1/2

(for anyone who needs the answer)​

Answer 1

x = 1/2

Explanation:

• -3x + 1 + 10x = x + 4 ⇒ simplify left side
• 7x + 1 = x + 4 ⇒ subtract x + 1 from both sides
• 7x - x = 4 - 1 ⇒ simplify
• 6x = 3 ⇒ divide both sides by 6
• x = 3/6 ⇒ simplify
• x = 1/2 ⇒ answer

Answer 2

`x=1/2`

Explanation:

So we have the equation:

`-3x+1=10x=x+4`

First, combine like terms on the left:

`7x+1=x+4`

Subtract 1 from both sides. The left cancels:

`(7x+1)-1=(x+4)-1\\7x=x+3`

Subtract x from both sides. The right cancels:

`(7x)-x=(x+3)-x\\6x=3`

Divide both sides by 6:

`(6x)/6=(3)/6\\x=1/2`

So, our answer is 1/2
