Question

 Tìm x

1. 540 : X + 126 :  X = 18

2. 4982 + X x 136 - 854 = 14328

Answer 1

1) 540 :x + 126 :x = 18

=> (540 + 126) : x = 18

=> 666 : x = 18

=> x = 666 : 18

=> x = 37

2) 4982 + x . 136 - 854 = 14328

=> 4128 + x . 136 = 14328

=> x . 136 = 14328 - 4128

=>x . 136 = 10200

=> x = 10200 : 136

=> x = 75

Answer 2

1.

540 : x + 126 : x = 18

x * (540 + 126)=18

x*666=18

x=1/37

Answer 3

 540 : X + 126 :  X \(=18\Rightarrow\frac{540}{\chi}+\frac{126}{\chi}=18\Rightarrow\frac{540+126}{\chi}=18\)

\(\Rightarrow\frac{666}{\chi}=18\Rightarrow\chi=666:18\Rightarrow\chi=37\)

Answer 4

1)540:x+126x=18

(540+126):x=18

666:x=18

x=666:18

x=37

2)4982+X x 136-854=14328

X x 136=14328+854-4982

X x 136=10200

X =10200:136=75

Answer 5

1) 540 :x + 126 :x = 18

=> (540 + 126) : x = 18

=> 666 : x = 18

=> x = 666 : 18

=> x = 37

2) 4982 + x . 136 - 854 = 14328

=> 4128 + x . 136 = 14328

=> x . 136 = 14328 - 4128

=>x . 136 = 10200

=> x = 10200 : 136

=> x = 75
