<span>Given :13-4x=1-x
Solution :
-4x+x=1-13 ( transfer -x to right side and change the sign from - to + ,the number 13 also when we transfer to the
left side you must change the sign from + to - ,then add of the the same sign the different sign
minus the bigger number will carry the sign)
-3x=-12
-3x/-3 = -12/-3 ( in order to get the x you divide the same number and sign both sides)
X = 4 answer</span>
8+4=12
9+7=16
12^2=144
16^2=256
144+256=400
square root of 400 is 20
therefore the distance from (8, -7) to (-4,9) is 20.
Answer: =28r−27
Step-by-step explanation:
The solution exist for the given equation are
x=-2
and
x=11/3
Answer:
6
Step-by-step explanation:
3x plus 12= 8x -18
subtract twelve on both sides:
3x= 8x- 30
minus 8x on both sides:
-5= -30
divide:6
