How to solve this equation 15 △ x = 10

15÷x=10
x=15÷10
x=1.5

How to solve the equation x (X-7) - 10 (X-7) = 0?

Extraction (X-7), (X-7) (X-10) = 0
So X1 = 7, X2 = 10

How to solve the equation of 15 (62 + x) = 270-60?

15(62+x)=270-60
930+15x=210
15x=720
x=48

How to solve the fractional equation of 10 / x + 15 / (x + 15) = 2 / 3,

10 × (x + 15) / X (x + 15) + 15x / X (x + 15) = 2 / 3 [10 × (x + 15) + 15x] / X (x + 15) = 2 / 3 (10x + 150 + 15x) / X (x + 15) = 2 / 3 (25X + 150) / (X & sup2; + 15x) = 2 / 32x & sup2; + 30x = 75X + 4502x & sup2; - 45x-450 = 0x = (45 ± root 5625) / 4x1 = 30x2 = - 7.5
