Question

Someone help I just got new assignments 23,24,25,26,27,28,29, and 30​

Answer 1

23: y = -0.4

24: b = -1.8

25: m = 1/2

26: g = 1/4

27: s = 3/2

28: w = -12/5

29: z = 5/4

30: a = -9/5

Explanation:

23:

• 
  `3y + 5.2 = -5y + 2`
• 
  `3y+5.2+5y=-5y+2+5y`
• 
  `8y + 5.2 = 2`
• 
  `8y+5.2-5.2=2-5.2`
• 
  `8y = -3.2`
• 
  `(8y)/(8) = (-3.2)/(8)`
• 
  `y = -0.4`

24:

• 
  `10b-2=7b-7.4`
• 
  `10b-2-7b=7b-7.4-7b`
• 
  `3b - 2 = -7.4`
• 
  `3b -2 + 2 = -7.4 + 2`
• 
  `3b = -5.4`
• 
  `(3b)/(3) = (-5.4)/(3)`

• 
  `b = -1.8`

25:

• 
  `2m - 2 = 6m - 4`
• 
  `2m-2-6m=6m-4-6m`
• 
  `-4m-2=-4`
• 
  `-4m-2+2=-4+2`
• 
  `-4m = -2`
• 
  `(-4m)/(-4) = (-2)/(-4)`
• 
  `m = (1)/(2)`

26:

• 
  `3g+5=7g+4`
• 
  `3g+5-7g=7g+4-7g`
• 
  `-4g+5=4`
• 
  `-4g + 5 - 5 = 4-5`
• 
  `-4g = -1`
• 
  `(-4g)/(-4) = (-1)/(-4)`
• 
  `g = (1)/(4)`

27:

• 
  `4s-1=-2s+8`
• 
  `4s-1+2s=-2s+8+2s`
• 
  `6s - 1 = 8`
• 
  `6s - 1 + 1 = 8+1`
• 
  `6s = 9`
• 
  `(6s)/(6) = (9)/(6)`
• 
  `s = (3)/(2)`

28:

• 
  `9w+3=4w-9`
• 
  `9w+3-4w=4w-9-4w`
• 
  `5w + 3=-9`
• 
  `5w + 3 - 3 = -9-3`
• 
  `5w = -12`
• 
  `(5w)/(5) = (-12)/(5)`
• 
  `w = (-12)/(5)`

29:

• 
  `6z-7=2z-2`
• 
  `6z-7-2z=2z-2-2z`
• 
  `4z -7 = -2`
• 
  `4z-7+7=-2+7`
• 
  `4z = 5`
• 
  `(4z)/(4) = (5)/(4)`
• 
  `z = (5)/(4)`

30:

• 
  `-a+3=4a+12`
• 
  `-a+3-4a=4a+12-4a`
• 
  `-5a+3=12`
• 
  `-5a + 3 - 3 = 12-3`
• 
  `-5a = 9`
• 
  `(-5a)/(-5) = (9)/(-5)`
• 
  `a = -(9)/(5)`
