Solving each equation for x:
1) 9 + x = 10x = 10 - 9x = 1
2) 16 - x = 8-x = 8 - 16-x = -8x = 8
3) x + 2 = 12x = 12 - 2x = 10
4) x - 6 = 6x = 6 + 6x = 12
Therefore, the solutions for each equation are:1) x = 12) x = 83) x = 104) x = 12
Solving each equation for x:
1) 9 + x = 10
x = 10 - 9
x = 1
2) 16 - x = 8
-x = 8 - 16
-x = -8
x = 8
3) x + 2 = 12
x = 12 - 2
x = 10
4) x - 6 = 6
x = 6 + 6
x = 12
Therefore, the solutions for each equation are:
1) x = 1
2) x = 8
3) x = 10
4) x = 12
