Question

If f(x)=-3x-2, find x so that f(x)=-9.5

Answer 1

X = -2.5 .

Explanation:

Here given,

- 3x-2

We have to find out the the x and from that value we should get -9.5. Let's see step by step solution:

=> 3x = 9.5 + 2 [ By replacing the position of - 2 from left side to right side]

=> 3x= -7.5

=> x =
`(-7.5)/(3)`

=> x= -2.5

Now putting the value in the place of x we get,

3 (-2.5) -2 = -9.5

So, the x will be -2.5 .
