We can solve each of these equations separately:
1) 43 + x = 64Subtract 43 from both sides:x = 64 - 43x = 21
2) 34 - x = 26Add x to both sides:34 = 26 + xSubtract 26 from both sides:8 = x
3) x + 45 = 59Subtract 45 from both sides:x = 59 - 45x = 14
4) x - 53 = 35Add 53 to both sides:x = 35 + 53x = 88
Therefore, the solutions are:x = 21, x = 8, x = 14, x = 88
We can solve each of these equations separately:
1) 43 + x = 64
Subtract 43 from both sides:
x = 64 - 43
x = 21
2) 34 - x = 26
Add x to both sides:
34 = 26 + x
Subtract 26 from both sides:
8 = x
3) x + 45 = 59
Subtract 45 from both sides:
x = 59 - 45
x = 14
4) x - 53 = 35
Add 53 to both sides:
x = 35 + 53
x = 88
Therefore, the solutions are:
x = 21, x = 8, x = 14, x = 88
