1) X + 3,75 = 17Subtract 3,75 from both sides:X = 13,25
2) 12,1 - x = 8,05Subtract 12,1 from both sides:-x = -4,05Multiply by -1 to solve for x:x = 4,05
3) X - 3,2 = 18,08Add 3,2 to both sides:X = 21,28
1) X + 3,75 = 17
Subtract 3,75 from both sides:
X = 13,25
2) 12,1 - x = 8,05
Subtract 12,1 from both sides:
-x = -4,05
Multiply by -1 to solve for x:
x = 4,05
3) X - 3,2 = 18,08
Add 3,2 to both sides:
X = 21,28
