∑ Hey, richiebustamante90 ⊃

Answer:

x = -8 or x = 2

Step-by-step explanation:

<u>→ Given ← :</u>

|3 + x| = 5

<u>→ Solution ← :</u>

Applying absolute rule ~:  \mathrm{If}\:|u|\:=\:a,\:a > 0\:\mathrm{then}\:u\:=\:a\:\quad \mathrm{or}\quad \:u\:=\:-a

Thus we have;    3+x=-5\quad \mathrm{or}\quad \:3+x=5

Solving each:

3+x=-5

3x-3=-5-3

x=-8

3+x=5

3-3+x=5-3

x=2

Hence, x=-8\quad \mathrm{or}\quad \:x=2

Answer:

x = - 8 , x = 2

Step-by-step explanation:

the absolute value function always gives a positive result, however, the expression inside can be positive or negative, , that is

x + 3 = 5 ( subtract 2 from both sides )

x = 2

or

-(3 + x) = 5

- 3 - x = 5 ( add 3 to both sides )

- x = 8 ( multiply both sides by - 1 )

x = - 8

What is the solution for x in the equation -4x+5x-7=10+3x-2x
jarptica [38.1K]
You combined the x’s together then u wanna move all the x’s to one side then after that you would want to do the opposite of -7, so then you add 7 to 10 and then you would divide everything by 2 and get x=8.5

Solve for x. *<br> (5x + 13)<br> (9x - 31)
ycow [4]

Answer:

x=11

Step-by-step explanation:

5x+13=9x-31

subtract 9 from both sides.

-4x+13=-31

you want to isolate the x value so subtract 13 from both sides.

-4x=-44

now divide both sides by -4.

x=11
