yo te ayudo, está fácil para mi :3 /
Explicación paso a paso:
Vertical
A) 3x + 2 = 32
3x = 32 - 2
3x = 30
X = 30 ÷ 3
X = 10
B) X = 16
5
X = 16(5)
X = 80
C) 2x + 8 = 440
2x = 440 - 8
2x = 432
X = 432 ÷ 2
X = 216
D) 2x - 9 = X + 262
2x - X = 262 + 9
X = 271
E) 9x + 9 = 900
9x = 900 - 9
X = 891 ÷ 9
X = 99
F) X - 2 = 250
4
X = 250 + 2
4
X = 252(4)
X = 1008
G) -2x + 10 = X - 989
-2x - X = -989 - 10
-X = -999
H) X + 5 = 2x - 80
5 + 80 = 2x - X
85 = X
horizontal
C) 5 . ( 2x - 1 ) - 10 = 235
10x - 5 - 10 = 235
10x = 235 + 15
X = 250
I) 8x - 968 = 7080
8x = 7080 + 968
X = 8048
J) X + 23 = - 52
-2
X = -52 - 23
-2
X = -75 (-2)
X = -150
K) 5x = 35745
X = 35745 ÷ 5
X = 7149
L) 4x - 4 = 3x + 6
4x - 3x = 6 + 4
X = 10
M) -2x + 8 = -360
-2x = -360 - 8
X = -368 ÷ -2
X = 180
N) X - 43 = 1000
9
X = 1000 + 43
9
X = 1043(9)
X = 9387
O) -4 . (-X + 10) = 4x+60
2
-5x -40 = 4x+60
2
2(-5x - 40) = 4x + 60
-10x - 80 = 4x + 60
-10x - 4x = 60 + 80
-14x = 140
X = 140 ÷ -14
X = -10
P) 5x + 4 + 3x + 4 = 8 + 4x
5x + 3x - 4x = 8 - 4 - 4
8x - 4x = 8 - 8
4x = 0
X = 0 ÷ 4
X = 0
