Solve 6+4r+2-9r - ScanMath

Evaluate

6 + 4 r + 2 - 9 r

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

6 + 4 r + 2 - 9 r = 0

Add the numbers

8 + 4 r - 9 r = 0

Subtract the terms

More Steps

8 - 5 r = 0

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

- 5 r = 0 - 8

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

- 5 r = - 8

Change the signs on both sides of the equation

5 r = 8

Divide both sides

\frac{5 r}{5} = \frac{8}{5}

Solution

r = \frac{8}{5}

Alternative Form

r = 1.6
