Answer

3\text{3}

Step-by-step solution

4 steps

  1. Substitute the given value of xx into the equation 2y+3x=152y + 3x = 15.

    We are given x=3x = 3.

    2y+3(3)=152y + 3(3) = 15

  2. Simplify the equation.

    2y+9=152y + 9 = 15

  3. Subtract 9 from both sides of the equation to isolate the term with yy.

    2y=15−92y = 15 - 9 2y=62y = 6

  4. Divide by 2 to find the value of yy.

    y=62y = \frac{6}{2} y=3y = 3

    The value of yy is 3\boxed{\text{3}}.
