Tìm x biết
a) - x - 14 +32 = -26
Cần gấp ạ
Tìm x: a, -15 + x = -14 - (-57)
b, (-14) + x - 7 = -10. c, -x - 14 + 32 = -26 d, x - (-19) - (-11) =0
a, -15 + \(x\) = -14 - (-57)
-15 + \(x\) = -14 + 57
\(x\) = -14 + 57 + 15
\(x\) = 58
b, (-14) + \(x\) - 7 = -10
\(x\) = -10 + 7 + 14
\(x\) = -3 + 14
\(x\) = 11
c, - \(x\) - 14 + 32 = -26
- \(x\) + 18 = -26
\(x\) = 18 + 26
\(x\) = 44
Tìm x: Cần gấp ạ
1, -15 + x= - 14 - (-57) 2,(-14) + x - 7 = -10 3, -x - 14 + 32 = -26 4, x-(-19) - (-11) = 0
1, -15 + \(x\) = -14 - (-57)
-15 + \(x\) = -14 + 57
\(x\) = -14 + 57 + 15
\(x\) = 43 + 15

Tìm số nguyên x biết:
a, −20+(𝑥−16)=−32
b, −42−7𝑥=−14
c, 26+|𝑥−15|=30
A, -20+ (x-16) = -32
-20 +x -16 = -32
-36 + x = -32
x = -32 - (-36)
x = 4
Vậy x= 4
B, -42 - 7x= -14
-7x=-42-(-14)
-7x = -28
x = -28 : (-7)
x = 4
Vậy x= 4
c, 26+|𝑥−15|=30
| x -15| = 4
TH1: x - 15= 4
x = 19
TH2: x - 15 = -4
x= 11
