X x Y = -48 and X + Y =9 So X = 9 - Y then (9 - Y) x Y = -48 then -YxY + 9 x Y = -48 or YxY - 9 Y - 48 = 0 (rewritten) Then use discriminant, Delta = (-9)x(-9) - 4 x 1 x -48 = 273 So Y = (9 - sqrt(273)) / 2 and X = 9 - Y = 9 - ((9 - sqrt(273)) / 2 OR Y = (9 + sqrt(273)) / 2 and X = 9 - Y = 9 - ((9 + sqrt(273)) / 2
x + x + 1 + x + 2 + x + 3 = -144x + 6 = 144x = 8x = 2

What is the variable of x plus 10 plus 4x-35?
x(x4+x3+x2+x+1)

The answer is 5x+3y. (5 xs and 3 ys)
4X
x=27
It is 123.99
x + x + 1 + x + 2 + x + 3 = -144x + 6 = 144x = 8x = 2
x+x+1+x+2+x+25=845 4x+28=845 4x=817 x=204.25
X= 5
