Question

X/-2=4, X/3+13=13, Z/2+2=4 plz show ur work and explain how u did it

Answer 1

`(x)/(-2)=4\ \ \ |multiply\ both\ sides\ by\ (-2)\\\\(-2)\cdot(x)/(-2)=(-2)\cdot4\\\\\boxed{x=-8}\\\\(x)/(3)+13=13\ \ \ |subtract\ 13\ from\ both\ sides\\\\(x)/(3)+13-13=13-13\\\\(x)/(3)=0\ \ \ |multpily\ both\ sides\ by\ 3\\\\\\ot3^1\cdot(x)/(\\ot3_1)=0\\\\\boxed{x=0}`


`(z)/(2)+2=4\ \ \ |subtract\ 2\ from\ both\ sides\\\\(z)/(2)+2-2=4-2\\\\(z)/(2)=2\ \ \ \ |multiply\ both\ sides\ by\ 2\\\\\\ot2^1\cdot(z)/(\\ot2_1)=2\cdot2\\\\\boxed{z=4}`
