How to solve the equation when x (X-2) = 24 Please teach me, I almost forgot my primary school things
X^2-2X-24=0
(X-6)*(X+4)=0
So x = 6 or - 4
1 -6
1 4
It's Cross multiplication
X + (x + 30) = 150
x+(x+30)=150 2x+30=150 2x=120 x=60
Solution equation: 150 / X-150 / X (1 + 25%) = 15 / 60
X=120
How to solve the equation: X-150% = x / 150%
x-1.5=x/1.5
(x-1.5x)/1.5=1.5
0.5x=1.5 ×1.5
x=1.5×1.5÷0.5
x=4.5
