x = -5 is the solution of equation 3x+2=x-8.
3x + 2 = x - 8
3x - x = -8 -2
2x = -10
x = -5
(i) the number line
Draw a line with measures represented in cm unit like a ruler.
From point 0 move towards left direction till 5 units and mark it as A.
Hence the required number line representation.
(ii) The Cartesian plane.
Mark a point on x-axis at x = -5 units.
Draw a vertical line on point x = -5 units.
Hence the required Cartesian plane representation.
