Answer:
X = 5
Step-by-step explanation:
28 = 7x + 3 - 2x
28 = 5x + 3
28 - 3 = 5x + 3 - 3
25 = 5x
25/5 = 5x/5
X = 5
Answer:
It would be -x

when you divide a positive by a negative you get a negative which singles out x.
-1x could be simplified down to just -x which singles out that answer too
Answer:
32
Step-by-step explanation:
do 4 x 3 = 12 then do 12 + 20 =32.
Answer: that would be a reflection
(x+2)(1-x)=-4
subtract 2 from both sides: x(1-x)=2
simplify:x-2x=2
subtract: -x=2
switch the negatives
x=-2
