Question

solve the following equations ​

Answer 1

Answer:

1. 7x - 5 = 2x

  7x-2x = 5

  5x/5 =5/5

  x = 1

2. 5x -12 =2x - 6

   5x -2x = -6 +12

  3x/3 =6/3

  x =2

3. 7p - 3 = 3p +8

  7p -3p =8 +3

   4p/4 =11/4

   p=2.75

4. 8m +9 =7m +8

  8m - 7m = 8 - 9

  m = -1

5. 7z +13 =2z +4

  7z -2z = 4 -13

   5z/5 = -9/5

   z= -1.8

6. 9y + 5 = 15y  - 1

   5 +1 = 15y -9y

   6/6 =6y/6

y= 1

7. 3x +4 = 5 (x-2)

   3x +4 = 5x -10

   14/2 =2x/2

   x =7

8. 3(t - 3)  = 5(2t -1)

   3t -9= 10t -5

   3t -10t =-5 +9

   -7t/7 = 4/7

  t= 0.57142857142
