Solve 4(3x-9)2-9=7

Evaluate

4 (3 x - 9) \times 2 - 9 = 7

Multiply the terms

8 (3 x - 9) - 9 = 7

Move the expression to the left side

8 (3 x - 9) - 9 - 7 = 0

Subtract the numbers

8 (3 x - 9) - 16 = 0

Calculate

More Steps

24 x - 88 = 0

Move the constant to the right-hand side and change its sign

24 x = 0 + 88

Removing 0 doesn't change the value,so remove it from the expression

24 x = 88

Divide both sides

\frac{24 x}{24} = \frac{88}{24}

Divide the numbers

x = \frac{88}{24}

Solution

x = \frac{11}{3}

Alternative Form

x = 3. \dot{6}
