Math Problem Statement

-4a=4+(2a+7)/-3

Solution

To solve the equation

4a=4+2a+73-4a = 4 + \frac{2a + 7}{-3}

we'll start by simplifying the right side and eliminating the fraction.

Step-by-Step Solution

  1. Simplify the Fraction:

    The equation is:

    4a=4+2a+73-4a = 4 + \frac{2a + 7}{-3}

    Rewrite the fraction:

    4a=42a+73-4a = 4 - \frac{2a + 7}{3}

  2. Eliminate the Fraction:

    Multiply every term by 3 to clear the fraction:

    3(4a)=3(42a+73)3(-4a) = 3 \left(4 - \frac{2a + 7}{3}\right)

    This simplifies to:

    12a=12(2a+7)-12a = 12 - (2a + 7)

    Distribute the negative sign on the right:

    12a=122a7-12a = 12 - 2a - 7

    Combine like terms:

    12a=52a-12a = 5 - 2a

  3. Solve for aa:

    Add 2a2a to both sides:

    12a+2a=5-12a + 2a = 5

    Simplify:

    10a=5-10a = 5

    Divide both sides by 10-10:

    a=12a = -\frac{1}{2}

Final Answer

a=12a = -\frac{1}{2}
