Yes. As there is no x² or higher term.
Actually, 3x+2=0 boils down to x=-2/3, and thus it's a vertical line on the graph paper going through -2/3 on the x axis
It is linear.
Yes.
7y+3x-21 =0 7y = -3x+21 y = -3/7x+3 The y intercept is 3
x2-5-4x2+3x = 0 -3x2+3x-5 = 0 or as 3x2-3x+5 = 0
3x + 2 = 0 3x = -2 x = -2/3
x2 plus 3x plus 3 is equals to 0 can be solved by getting the roots.
the answer is -3x = 0
x = 0
x = y = 0 ?
-2
5x = 3x+1000+0 5x-3x = 1000 2x = 1000 x = 500
6-3x+12=0 6+12-3x=0 18-3x=0 18=3x x=6
