Answer:
7/2
Step-by-step explanation:
12x=4(x+2)+20
12x=4x+8+20
12x-4x=8+20
8x=28
x=28/8
simplify
x=7/2
Answer:
NO IT WOULD BE 0
Step-by-step explanation:
Answer: 1. X+2
2. 6x-3
3. -2x-1
4. 9x5
Step-by-step explanation:
1. X+4-3+1 There is only one variable, so you don’t need to worry about that. Just do all of the numerical operations. 4-3+1= 2. So it would be x+2
2. X-5+5x+2. Again, do the numerical operations first. -5+2=-3. X+5x=6x. So it would be 6x-3.
3. 2x+7-4x-8. 7-8=-1. 2x-4x=-2x. So it would be -2x-1.
4. (4+3)x+2x-5. Do the operation in the parenthesis first. Then it would be (7)x or just 7x+2x-5. Simplify to 9x-5.
Answer:
x<-11/2
Step-by-step explanation
Try to isolate the variable by dividing it.
