X-120 = 80% x + 0.375x (solving equation)

X-120 = 80% x + 0.375x (solving equation)

X-120 = 80% x + 0.375xx-120 = 0.8x + 0.375x (transfer) x-0.8x-0.375x = 1200.175x = - 120x = - 120 / 0.175x = - 120000 / 175x = - 4800 / 7 or x-120 = 4x / 5 + 3x / 8x-4x / 5-3x / 8 = 120 (40x-32x-15x) / 40 = 120-7x / 40 = 1207x = - 4800 = - 4800 / 7

Solution equation: (x + 1200) △ 200 = (x-1200) △ 80
Good answer, there is a reward,

（X+1200）÷200=（X-1200）÷80
（X+1200）÷5=（X-1200）÷2
（X+1200）*2=（X-1200）*5
2X+2400=5X-6000
(5-2)X=6000+2400
3X=8400
X=2800

What's 28 divided by 25

28 / 25 (28 / 25)

925 divided by______ Business 24 more than 13

From the formula: divisor = divisor × quotient + remainder, divisor = (divisor remainder) △ quotient, (925-13) △ 24, = 912 △ 24, = 38, so the answer is: 38
