x/6+3000-x/4=600

x/6+3000-x/4=600


x/6-x/4=-2400
2x/12-3x/12=-2400
-x/12=-2400
x=12*2400
x=28800



Solve the equation x (1 + 25%) + (3000-x) (1-25%) = 3000 × (1 + 15%)


1.25x+2250-0.75x=3450



Solving equation 25% x-4.2 = 15% x + 1.8


25%x-4.2=15%x+1.8
0.25x-4.2=0.15x+1.8
0.25x-0.15x=1.8+4.2
0.1x=6
x=60



Solving equation 25 × 4 = (25 + 15) × x


25×4=(25+15)×x
100=40x
x=100/40
x=2.5
