Question

What is x if `-3/4(x+2)=-1`?

Answer 1

I found `x=-2/3`

Explanation:

Basically here you want the value of `x` that makes the left side equal to the right. You could try to guess but is complicated...
You can try instead to isolate `x` on one side (the left, for example) and "read" the result.

Remember that everything that passes through the equal sign has to change sign!
If it was a sum it becomes a subtraction;
if it was a multiplication it becomes a division...and vice versa;
In your case:
`-3/4` is multiplying the bracket, so it goes to the right as a division:
`(x+2)=-1/(-3/4)`
the `2` is a sum so it goes to the right as a subtraction:
`x=-1/(-3/4)-2` now we can rearrange to simplify a bit the right side and write:
`x=-1*(-4/3)-2`
`x=4/3-2`
`x=(4-6)/3=-2/3`

You can now try to substitute this value of `x` into your original equation to see if it satisfies it!!!
