x = 0
if 3x+7 = 3 then 3x = 3-7 3x = -4 then, x = -4/3
equivalent to 3x -6 = -9; so 3x = -9 + 6; so 3x = -3 so x = -1. Check: -6 + (3 * -1) = -6 + (-3) = -9 QED
5x+3 = 3x+11 5x-3x = 11-3 2x = 8 x = 4
3+3x+7x=13 3x+7x=10 10x=10 x=1
x = 0
equivalent to 3x -6 = -9; so 3x = -9 + 6; so 3x = -3 so x = -1. Check: -6 + (3 * -1) = -6 + (-3) = -9 QED
if 3x+7 = 3 then 3x = 3-7 3x = -4 then, x = -4/3
x2 plus 3x plus 3 is equals to 0 can be solved by getting the roots.

3x+7=37 -7 -7 3x=30 /3 /3 x=10
5x+3 = 3x+11 5x-3x = 11-3 2x = 8 x = 4
It depends on what it is meant to be equivalent to!
3+3x+7x=13 3x+7x=10 10x=10 x=1
3x + 11 = x + 3 2x = -8 x = -4
2x+3 = 3x+5 2x-3x = 5-3 -x = 2 x = -2
y = 3x + 6slope = 3
