Question

tìm X:

a) X + 3,12 = 14,6 - 8,5

b) X - 5,14 = (15,7 +2,3) . 2

Answer 1

a) x+3,12=14,6-8,5
    x+3,12=6,1
    x         = 6,1-3,12
    x         = 2,98
b) x-5,14=(15,7+2,3).2
    x-5,14=36
    x        = 36+5,14
    x        = 41,14

Answer 2

a,x+3.12=6.1

x=6.1-3.12

x=2.98

b,x-5.14=36

x=36+5.14

x=41.14

Answer 3

a)  X + 3,12 =  6.1

X = 6.1 - 3.12

X=  2,98

b) X - 5,14 = 36

X = 36 + 5.14

X = 41.14

Answer 4

a. \(x+3,12=14,6-8,5\\x+3,12=6,1\\ x=6,1-3,12\\ x=2,98 \)

b. \(x-5,14=\left(15,7+2,3\right).2\\ x-5,14=36\\ x=36+5,14\\ x=41,14\)
