Question

Solve the following and check your results. EQUATIONS HAVING THE VARIABLE ON BOTH SIDES (a) 2x – 3 = x + 2 (g) 2.8 v = 54 + v (b) 8x – 11 – 5x + 3 = 2x + 4 – 3x (h) 5x – 7 = 2x + 8

Answer 1

Answer:

Step-by-step explanation:

a. 2x-3=x+2

   2x-x=2+3

   x=5

b. 8x-11-5x+3=2x+4-3x

   8x-2x+3x=4-3+11

   9x=12

   x=12/9

   x=4/3

g. 2.8v=54+v

   2.8v-v=54

   1.8v=54

   v=54/1.8

   v=30

h. 5x-7=2x+8

   5x-2x=8+7

   3x=15

   x=15/3

   x=5

Answer 2

Solve the following:      x – 2= 7

Answer:

Given, x -2 = 7

=> x – 2 + 2= 7 + 2    [Adding 2 both sides]

=> x = 9by-step explanation:
