welcome to e-learning 2014

Mr Yong - 1st question

yong_jui_jin — 2014-04-07 01:17:18 UTC

Solve 2x + 1 = 3

Mr Yong - 2nd Question

yong_jui_jin — 2014-04-07 01:24:10 UTC

Solve

1.) 5x + 3 = 4(x+ 7)

2.) 5x + 3 = 4x + 28

3.) 5x +3 -3 = 4x +28 - 3

4.) 5x = 4x +25

5.) 5x- 4x = 4x -25 -4x

6.) x = 25 (ANSWER!)

Mr Yong

yong_jui_jin — 2014-04-07 01:42:48 UTC

Multiply both sides by the denominator

Answer to question:

9-(4x/3)= -7

(9-4x/3)x3= -7x3

9-4x=-21x

Good Afternoon :)

Hanna ( 5th question )

9 - (4x/3) = -7

9 - (4x/3) x 3 = -7 x 3

27 - 4x = -21

27 + 21 - 4x = -21 +21

48 - 4x = 0

48 - 4x + 4x = 0 + 4x

48 = 4x

12 = x

Mr Yong 5th Question (incomplete)

yong_jui_jin — 2014-04-09 04:01:26 UTC

9 -(4x/3) = -7

multiply by 3 on both sides

3[ 9 - (4x/3 ] = -21

27 -

Mr Yong's 6th question

yong_jui_jin — 2014-04-09 04:19:06 UTC

(y/5) - (y+2)/7 = 2

Hanna

2014-04-09 04:19:32 UTC

(y/5) - (y+2)/7 = 2

(y/5) - (y+2)/7 x 5 = 2 x 5

y - (y+2)/35 = 10

y - (y+2)/35 x 35 = 10 x 35
