Question

solve the following


c)3(x+6)+2(x+3)=54
d)6x+5=3x+20
e)19x-3=11x+35​
​

Answer 1

Answer:

Step-by-step explanation:

3(x+6) + 2(x+3) = 54

3x + 18 + 2x + 6 = 54

5x + 24 = 54

5x = 54 - 24

5x = 30

x =  6

6x + 5 = 3x + 20

6x - 3x = 20 - 5

3x = 15

x = 5

19x - 3 = 11x + 35

19x - 11x = 35 + 3

8x =38

x = 38/8

x = 4.75

Answer 2

Answer:

c) 3(x+6)+2(x+3)=54

=> 3x + 18 + 2x + 6 = 54

=> 5x + 24 = 54

=> 5x = 54-24

=> x = 30/5 = 6

d)6x+5=3x+20

=> 6x - 3x = 20 - 5

=> 3x = 15

=> x = 15/3 = 5

e)19x-3=11x+35

=> 19x - 11x = 35 + 3

=> 8x = 38

=> x = 38/8 = 19/4
