Math Problem Statement

-6 (y-2) = 4(y-9)

Solution

Let's solve the equation step by step:

6(y2)=4(y9)-6(y - 2) = 4(y - 9)

Step 1: Distribute on both sides

Distribute 6-6 and 44 to the terms inside the parentheses:

6y+12=4y36-6 \cdot y + 12 = 4 \cdot y - 36

This simplifies to:

6y+12=4y36-6y + 12 = 4y - 36

Step 2: Move all terms involving yy to one side

Add 6y6y to both sides to bring the yy-terms together:

12=10y3612 = 10y - 36

Step 3: Move the constant terms to the other side

Add 36 to both sides to move the constant to the other side:

48=10y48 = 10y

Step 4: Solve for yy

Now, divide both sides by 10:

y=4810=4.8y = \frac{48}{10} = 4.8

Thus, the solution is:

y=4.8y = 4.8
