Step-by-Step Solution

To solve the equation 4y7+6y=310y 4y - 7 + 6y = 3 - 10y , follow these steps:

  • Step 1: Combine like terms on both sides of the equation.

The left side simplifies by combining the y y -terms:
4y+6y7=10y7 4y + 6y - 7 = 10y - 7 .

On the right side, there is one y y -term, but we can leave it for the next steps.

  • Step 2: Isolate the y y -terms.

Add 10y 10y to both sides to move all y y -terms to the left side:

10y7+10y=3 10y - 7 + 10y = 3

Simplifying the left side, we get:

20y7=3 20y - 7 = 3

  • Step 3: Isolate y y .

Add 7 7 to both sides to eliminate the constant term on the left:

20y=3+7 20y = 3 + 7

20y=10 20y = 10

Divide both sides by 20 20 to solve for y y :

y=1020 y = \frac{10}{20}

y=12 y = \frac{1}{2}

Therefore, the solution to the problem is y=12 y = \frac{1}{2} .

Answer

12 \frac{1}{2}
