21x - 19 = 3x + 17   |add 19 to both sides
21x = 3x + 36    |substract 3x from both sides
18x = 36     |divide both sides by 18
x = 2

Which system of equations can you use to find the roots of the equation? x3 – 10x = x2 – 6 y = x3 – x2 + 10x + 6 y = 0 y = x3 –

Maslowich

Answer:

answer is:

$y=x^{3}-10 x,y=x^{2}-6$

Step-by-step explanation:

we are asked to find which system of equations can we use to find the roots of the equation:

$x^{3}-10x=x^{2}-6$

since the system of equation in last part is given as:

$y=x^{3}-10 x,y=x^{2}-6$

so, on equating both the equations i.e. on equating both the values of 'y' we get the desired equation as:

$x^{3}-10x=x^{2}-6$ .
