Simplify : 12+-5x+6x=4 combine like terms : -5x+6x=1x 12+1x=4 solving : 12+1x=4 solving for variable ‘x’ move all terms containing x to the left, all other terms to the right, add ‘-12’ to each side of the equation 12+-12+1x=4+-12 combine like terms: then divide each side your answer : x=-8
SE is hypotenuse so with having <span>coordinates of S and E we can say midpoint is (6+0/2,8+0/2)=(3,4) i really don't know what are those options </span>
