Math Problem Statement

6(3 x -5) = 2(2 x + 4)

Solution

Let's solve the equation:

6(3x5)=2(2x+4)6(3x - 5) = 2(2x + 4)

Step 1: Expand both sides of the equation.

On the left-hand side: 6(3x5)=6×3x6×5=18x306(3x - 5) = 6 \times 3x - 6 \times 5 = 18x - 30

On the right-hand side: 2(2x+4)=2×2x+2×4=4x+82(2x + 4) = 2 \times 2x + 2 \times 4 = 4x + 8

So the equation becomes: 18x30=4x+818x - 30 = 4x + 8

Step 2: Move all the terms with xx to one side and constant terms to the other.

Subtract 4x4x from both sides: 18x4x30=818x - 4x - 30 = 8 14x30=814x - 30 = 8

Step 3: Isolate xx.

Add 30 to both sides: 14x=8+3014x = 8 + 30 14x=3814x = 38

Step 4: Solve for xx.

Divide both sides by 14: x=3814=197x = \frac{38}{14} = \frac{19}{7}

Thus, the solution is: x=197x = \frac{19}{7}
