If you mean x/2 + y/3 = 0 (ZERO, not the letter O) then yes.
The equation can be rewritten as x/2 = - y/3 or x = (-2/3)y
Because in any case of 1/2x, you have to multiply the other end of the sum with two. (so 4 7/8 times 2). It has to be more than 4 7/8, ergo: it can not be 7/8
5x**2-30x-801. Remove common term (and ignore til end):5(x**2-6x-16)2. Multiply first and third terms1*-16=-163. Factor product of first and third terms-16, 1-8, 2-4, 416, -18, -24. Choose factors whose sum is equal to second term-8+2=-65. Rewrite equation using factorsx**2-8x+2x-166. Halve the expressionx**2-8x2x-167. Factor each halfx**2-8x --> x(x-8)2x-16 --> 2(x-8)8. Recombinex(x-8)+2(x-8)9. Factor out common term:(x-8)(x+2)10. Reintroduce part from beginning5(x-8)(x+2)
