Answer:

5.)

15.36+x=32.11

15.36+x-15.36=32.11-15.36

x=32.11-15.36

x=16.75

6.)

-2(a-3b+c)

-2a+6b-2c

7.)

3a+15y-5a=-a+2(3-a)

-2a+15y= -a+6-2a

-2a+15y=-3a+6

-2a+15y+2a=-3a+6+2a

15y=-a+6

15y/15=-a+6/15

y=-a+6/15

I hope this is good enough:

-4|x-11|=-16 solve for x in the equation
BigorU [14]

Answer:

x = 7 and 15

Step-by-step explanation:

Divide both sides by -4...

| 4 | = 4

x - 11 = -4 and x - 11 = 4

solve for x in both equations.

x = 7 and x = 15

Solve the inequality.<br><br> 2(4x – 3) ≥ –3(3x) + 5x?
slega [8]
2(4x-3) ≥ - 3(3x) + 5x

2* 4x - 2*3 ≥ - 9x + 5x

8 x - 6 ≥ -4x

8 x + 4 x ≥ 6

12 x ≥ 6

x = 6/12 divide 6/6 = 1 and 12 / 6 = 2

x = 1/2 

hope this helps!
