Answer:
equation- 4÷x=-7
x= -4/7
Step-by-step explanation:
Ok so first following the order of opperation (P.E.M.D.A.S.)
We have to multiply first so 1/4*4/9 is 4/36
2/3-4/36
We have to get them both to have the same denominator
What times 3 is 36? 12
So multiply 2*12 and 3*12 you get
24/36-4/36=5/9(simplified)
The expression is 8x-(5x+8)
The simplifies is 3x-8 because 8x-(5x+8)=8x-5x-8 and 8x-5x=3x
