-8 plus 6f equals -5

Answer 1

the variable "f" is equal to half (or 0.5)

-8 + 6f = -5

you must isolate the "6f" to find the value of "f" alone

First, you must move the negative 8 to the right side.

since 8 is negative on the left side, it becomes positive 8 on the right side.

i.e. 6f = -5 +8

negative 5 plus 8 is equal to 3.

i.e. 6f = 3

you must now divide the left side and right side to find the value of 1 f instead of 6f's.

we divide by the number next to the variable which in this case is 6.

i.e 6f / 6 = 3 / 6

f = 0.5

6f divided by 6 = 1f ( or just f ) and 3 divided by 6 is 0.5 ( or 1/2 )

therefore f = 0.5
