Question

Solve the equation f/4-5= -9

Answer 1

f= -16

Explanation:

`f/4-5= -9\\\\(f)/(4)-5=-9\\\\\mathrm{Add\:}5\mathrm{\:to\:both\:sides}\\\\(f)/(4)-5+5=-9+5\\\\Simplify\\\\(f)/(4)=-4\\\\\mathrm{Multiply\:both\:sides\:by\:}4\\(4f)/(4)=4\left(-4\right)\\\\Simplify\\f=-16`

Answer 2

f = -16

Explanation:

f/4-5= -9

Add 5 to each side

f/4-5+5= -9+5

f/4 = -4

Multiply each side by 4

f/4 *4 = -4 *4

f = -16
