Tìm x, biết: a, 24 × x = 101,3 – 12,5 b, 11 × x = 38,26 + 31,26 c, (x + 9,2) × 24 = 292,32

a,
24 × x = 101,3 – 12,5
24 × x = 88,8
x = 88,8 : 24
x = 3,7
b,
11 × x = 38,26 + 31,26
11 × x = 69,52
x = 69,52 : 11
x = 6,32
c, (x + 9,2) × 24 = 292,32
x + 9,2 = 292,32 : 24
x + 9,2 = 12,18
x = 12,18 – 9,2
x = 2,98
