3x-11 for x=9

(0,7)

3x+5=20 3x=15 x=5

7

3x+5=7x-11 5=4x-11 4x=16 x=4

3x 11 5x=75 x=8

x2 plus 3x plus 3 is equals to 0 can be solved by getting the roots.

3x + 2y = 12 ie 2y = 12 - 3x so y = 6 - 3x/2

23

x=7

3

x = -8

3x + 9 = 42 3x = 33 x = 11

4+3x-27=-12 To solve it... 3x= -12-4+27 3x= 11 x= 11/3 x= 3.666

4y = 3x+11 or as y = 3/4x+11/4

2x + 3 + 3x = x + 11 5x + 3 = x + 11 4x + 3 = 11 4x = 8 x = (8/4) x = 2

x = 6

x = -8

3x+11+5x=75(add 5x and 3x) 8x+11=75(-11) 8x=64(/ 8) x=8(ANSWER)

x + 2x = 33 3x = 33 3x/3 = 33/3 x = 11

9x + 3x - 9x = 6 + 8x - 113x = 8x - 11-5x = -11x = 2.2 or 11/5

x=-11

172=x

X = 12
