Answer:

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:


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
