A)12+4+x < 20
B)32.32+x >32
C)98+4 ≠ x +100
D)X + 64+45 < 105+5
E)12/3 + 12 + x >72
F)x+x+44>160

Answer 1

12 + 4 + x < 20
x + 16 < 20
x < 20 - 16
x < 4
=================================
32 . 32 + x > 32
1024 + x > 32
x > 31 - 1024
x > - 993
==================================================
98 + 4  #  x + 10    # é diferente
102 # x + 10
- x # 10 - 102
- x # - 92  . (-1)
x # 92
=====================================
x + 64 + 45 < 105 + 5
x + 109 < 110
x < 110 - 109
x < 1
=============================================
12/3 + 12 + x > 72
x > 72 - 12 - 12/3
x > 60 - 12/3             mmc = 3
x > 180/3 -12/3
x > 168/3
x = 56
===============================================
x + x + 44 > 160
2x + 44 > 160
2x > 160 - 44
2x > 116
x > 116/2
x > 58
