Solve 10x - (5x-7)

Evaluate

10 x - (5 x - 7)

To find the roots of the expression,set the expression equal to 0

10 x - (5 x - 7) = 0

Subtract the terms

More Steps

5 x + 7 = 0

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

5 x = 0 - 7

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

5 x = - 7

Divide both sides

\frac{5 x}{5} = \frac{- 7}{5}

Divide the numbers

x = \frac{- 7}{5}

Solution

x = - \frac{7}{5}

Alternative Form

x = - 1.4

10x (5x 7)
