answer all with complete solution

Solution

Let's solve each problem step-by-step.

Problem 1

5x=355x = 35 To solve for xx, divide both sides by 5: x=355=7x = \frac{35}{5} = 7 Answer: x=7x = 7


Problem 2

24=3x24 = -3x To solve for xx, divide both sides by -3: x=243=8x = \frac{24}{-3} = -8 Answer: x=8x = -8


Problem 3

14c+15=43+7c14c + 15 = 43 + 7c

  1. Move 7c7c to the left side by subtracting 7c7c from both sides: 14c7c+15=4314c - 7c + 15 = 43 7c+15=437c + 15 = 43
  2. Subtract 15 from both sides: 7c=287c = 28
  3. Divide by 7: c=4c = 4 Answer: c=4c = 4

Problem 4

5(2y1)=2(4y3)5(2y - 1) = 2(4y - 3)

  1. Expand both sides: 10y5=8y610y - 5 = 8y - 6
  2. Move 8y8y to the left side by subtracting 8y8y from both sides: 10y8y5=610y - 8y - 5 = -6 2y5=62y - 5 = -6
  3. Add 5 to both sides: 2y=12y = -1
  4. Divide by 2: y=12y = -\frac{1}{2} Answer: y=12y = -\frac{1}{2}

Problem 5

5p+6(p+7)=3(p+2)5p + 6(p + 7) = 3(p + 2)

  1. Expand both sides: 5p+6p+42=3p+65p + 6p + 42 = 3p + 6 11p+42=3p+611p + 42 = 3p + 6
  2. Move 3p3p to the left side by subtracting 3p3p from both sides: 11p3p+42=611p - 3p + 42 = 6 8p+42=68p + 42 = 6
  3. Subtract 42 from both sides: 8p=368p = -36
  4. Divide by 8: p=368=92p = -\frac{36}{8} = -\frac{9}{2} Answer: p=92p = -\frac{9}{2}

Problem 6

[ 32 - [4 + 6x - 5(x + 4)] = 4(3x + 4) - [6(3x - 4) + 7 - 4x] ]

  1. Start by expanding within the brackets on both sides.

For the left side: 32[4+6x5x20]32 - [4 + 6x - 5x - 20] =32[16+x]= 32 - [ -16 + x] [
