Solve (14r - 12) - (-2r - 5)

Question

Simplify the expression

16 r - 7

Evaluate

(14 r - 12) - (- 2 r - 5)

Remove the parentheses

14 r - 12 - (- 2 r - 5)

If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses

14 r - 12 + 2 r + 5

Add the terms

More Steps

Evaluate

14 r + 2 r

Collect like terms by calculating the sum or difference of their coefficients

(14 + 2) r

Add the numbers

16 r

16 r - 12 + 5

Solution

16 r - 7

Show Solution

Find the roots

r = \frac{7}{16}

Alternative Form

r = 0.4375

Evaluate

(14 r - 12) - (- 2 r - 5)

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

(14 r - 12) - (- 2 r - 5) = 0

Remove the parentheses

14 r - 12 - (- 2 r - 5) = 0

Subtract the terms

(14 + 2) r

Add the numbers

16 r

16 r - 12 + 5

Add the numbers

16 r - 7

16 r - 7 = 0

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

16 r = 0 + 7

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

16 r = 7

Divide both sides

\frac{16 r}{16} = \frac{7}{16}

Solution

r = \frac{7}{16}

Alternative Form

r = 0.4375
