25x + 75 = 25*(x + 3)
Factorise to (x-1)(x-24)=0 then either x-1 = 0 or x-24 = 0 so x=1 or x=24
5x-15y = -10
15y^8 - 7y^3 = y^3(15y^5 - 7)
15y+14=2(5y+6) 15y+14=10y+12 15y+14-14=10y+12-14 15y=10y-2 15y-10y=10y-2-10y 5y=-2 y=-2/5
25x + 75 = 25*(x + 3)
15 y + 20 = 5(3y + 4)
Factorise to (x-1)(x-24)=0 then either x-1 = 0 or x-24 = 0 so x=1 or x=24
5x-15y = -10
25x-32 = 7 25x-9 = 7 25x = 7+9 25x = 16 x = 16/25
GCF(15y, 25) = 5.
32 + 25x + 18 = 50 + 25x
3xy-4x + 15y-20 Sol: As there are no number are same. So -4x-3xy +15y-20 -------------------- -4x-3xy+15y-20
15y^8 - 7y^3 = y^3(15y^5 - 7)
15y+14=2(5y+6) 15y+14=10y+12 15y+14-14=10y+12-14 15y=10y-2 15y-10y=10y-2-10y 5y=-2 y=-2/5
25x'2
x/5y + 2x/3y = 3x/15y + 10x/15y = 13x/15y
