9x - 9 = 36 9x = 45 x = 5
8x + 9x = x(8 + 9) = x(17) = 17x
Integral : 9x + 8 = 9(x squared)/2 + 8x Differential : 9x +8 = 9
2x2 - 9x = 18 2x2 - 9x -18 = 0 (2x - 18)(x + 9) x= -9 and 9
-8x+7 = -7x-2 -8x = -7x-2-7 -8x=-7x-9 -8x+7x=-9 -1x=-9 x=-9/-1 x=9
8x+9=9x-18+9 = 8x+9=9x-9 = 1x=0 (:
9x = 100 - 30 + 11 9x = 81, x = 9
X equals 9.
9x - 9 = 36 9x = 45 x = 5
8x + 9x = x(8 + 9) = x(17) = 17x
Integral : 9x + 8 = 9(x squared)/2 + 8x Differential : 9x +8 = 9
8x + x = 1 -8x + 3x = -3 Clean up 9x = 1 -5x = -3 x = 1/9 x = 3/5 Two different answers. If you were expected to solve them simultaneously, this would be an incompatible set, returning an answer of {Φ} ■
sqrt(9x-9) + 5 = 10Subtract 5 from each side:sqrt(9x-9) = 5Square each side:9x - 9 = 25Add 9 to each side:9x = 34Divide each side by 9:x = 34/9 or 3-7/9
9x-5 = 13 Add 5 to both sides: 9x = 18 Divide both sides by 9: x = 2
x = 5
it's an easy one :)-6 - 6x = 9 - 9x-6x + 9x = 9 + 63x = 15x = 15/3X = 5
Centre of circle: (2, 1.25) Slope of line: 9/4 Equation of line: y-1.25 = 9/4(x-2) => 4y-5 = 9x-18 => 4y = 9x-13
