13=x(-4)
How am I supposed to solve that ?
\(13=x(-4) \)
Do you mean
\(1) \qquad 13=x\times (-4)\\ 2) \qquad 13=x-4\\ or\\ 3) \qquad 13=x^{ -4}\\\)
Answer my question and then I can answer yours :)
13=x(-4) or 13=-4x
Then we divide by -4 on both sides to take your -4 as your coefficient 13=-4/-4x
so the answer would be
x=-13/4 or x=-3.25
