x =
x + 17 = 33
x
x + 4 = 11

x + 19 = 31
x =
x + 12 = 56
x =
x + 45 = 89
x =

x + 195 = 316
x =
x + 91 = 112
x =
x + 77 = 102
x =

Explanation:

First row:

First equation ($x + 75 = 123$):

Step1: Subtract 75 from both sides

$x + 75 - 75 = 123 - 75$

Step2: Simplify

$x = 48$

Step1: Subtract 17 from both sides

$x + 17 - 17 = 33 - 17$

Step2: Simplify

$x = 16$

Step1: Subtract 4 from both sides

$x + 4 - 4 = 11 - 4$

Step2: Simplify

$x = 7$

Answer:

48

Second equation ($x + 17 = 33$):
