Toán Lớp 6: a) 3 + x = – 8

a) 3 + x = -8
=> x = -8 – 3
=> x = -11
b) 110 – 2x = 10
=> 2x = 110 – 10
=> 2x = 100
=> x = 100 : 2
=> x = 50
c) (35 + x) – 12 = 27
=> 35 + x = 27+12
=> 35 + x = 39
=> x = 39 – 35
=> x = 4
d) 96 : 2x + 2 = 3
Giải đáp:
a) x = -11
b) x = 50
c) x = 4
d) x = 48
Lời giải và giải thích chi tiết:
a) 3 + x = -8
x = -8 – 3
x = -11
Vậy x = -11
_______________
b) 110 – 2x = 10
2x = 110 – 10
2x = 100
x = 100 : 2
x = 50
Vậy x = 50
_______________
c) (35 + x) – 12 = 27
35 + x = 27 + 12
35 + x = 39
x = 39 – 35
x = 4
Vậy x = 4
________________
d) 96 : 2x + 2 = 3
96 : 2x = 3 – 2 = 1
2x = 96 : 1
2x = 96
x = 96 : 2
x = 48
Vậy x = 48
