x=7

3

x = -8

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

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

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

x = 6

x = -8

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

7x = 3x - 12 4x=-12 x=-3

x = 5, y = -1

172=x

X = 12

3x + 4= 7 3x= 7-4 3x/3 = 3/3 x=1

solve -3x-3y=-15

3x+4 = 2x-3 3x-2x = -3-4 x = -7

3x+2y=6 2y=-3x+6 y=-1.5x+3

4x+7-3x = 15 4x-3x = 15-7 x = 8

g (x) = -3x+5 -3x= 5 x= -5/3

y-3x+6y=12 7y=3x+12 y=3x/7 +12/7

You cannot solve one linear equation in two unknown variables.

5x+y=-7 3x+y=15 8=D

no

x = 4 and y = 0
