solve 2|x+1|=8
2 answers:
Answer:
x = 3 x = -5
Step-by-step explanation:
2|x+1|=8
Divide each side by 2
2/2|x+1|=8/2
|x+1| = 4
There are two solutions to an absolute value, one positive and one negative
x+1 = 4 x+1 = -4
Subtract 1 from each side
x+1 -1 = 4-1 x+1-1 = -4-1
x = 3 x = -5
Answer:
x=3 and -5
Step-by-step explanation:
to start with when you work with equations there will be two answers, no solution set or the answer will be 0. in this case there are two answers.
<u>2/x+1</u>/=<u>8(first you remove all the things that are extra to the equation)</u>
2 2
/x+1/=4 in this case it has two answers because 4 is greater than 0.
so you remove the bracket.
x+1=4 or x+1=-4
x=4-1 x=-4-1
x=3 x=-5

X+5y=12
yint is where the line crosses the y axis or where x=0
set x=0 and solve for y
0+5y=12
5y=12
divide both sides by 5
y=12/5
ying=12/5
