5(5x - 3) = 5(3x + 7)
There is no need to distribute, simply divide both sides by five
5x - 3 = 3x + 7
subtract 3x from both sides
2x - 3 = 7
add 3 to both sides
2x = 10
divide both sides by 2
x = 5
g (x) = -3x+5 -3x= 5 x= -5/3
3x + 9 = 42 3x = 33 x = 11
x=7
23
-3x + 5 = 20 -3x = 15 x = -5
g (x) = -3x+5 -3x= 5 x= -5/3
3x + 9 = 42 3x = 33 x = 11
3
23
x=7
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
-15x=-5*3x+2 -15x=-15x+2 +15x +15x ----------------- 0=2
3x + 2y = 12 ie 2y = 12 - 3x so y = 6 - 3x/2
x = -8
x = 6
