To solve these equations:
1) 69 - x = 43Subtract 69 from both sides:-x = -26Divide by -1 to solve for x:x = 26
2) x - 21 = 42Add 21 to both sides:x = 63
3) 28 + x = 59Subtract 28 from both sides:x = 31
4) 56 - x = 43Subtract 56 from both sides:-x = -13Divide by -1 to solve for x:x = 13
5) x - 15 = 25Add 15 to both sides:x = 40
Therefore, the solutions are:1) x = 262) x = 633) x = 314) x = 135) x = 40
To solve these equations:
1) 69 - x = 43
Subtract 69 from both sides:
-x = -26
Divide by -1 to solve for x:
x = 26
2) x - 21 = 42
Add 21 to both sides:
x = 63
3) 28 + x = 59
Subtract 28 from both sides:
x = 31
4) 56 - x = 43
Subtract 56 from both sides:
-x = -13
Divide by -1 to solve for x:
x = 13
5) x - 15 = 25
Add 15 to both sides:
x = 40
Therefore, the solutions are:
1) x = 26
2) x = 63
3) x = 31
4) x = 13
5) x = 40
