Answer:
8) i have no clue
9) x=36
10) x=10
Explanation:
9) 73-1=72
72/2=36
x=36
10) 3x+7
90-53=37
37-7=30
30/3
x=10
8 x = 17
9 x = 36
10 x = 10
8
(6x + 5) + (4x+5) = 180
6x + 4x = 180 - 5 - 5
10x = 170
x = 170/10
x = 17
9
2x + 1 = 73
2x = 73 - 1
2x = 72
x = 72/2
x = 36
10
(3x+7) + 53 = 90
3x = 90 - 53 - 7
3x = 90 - 60
3x = 30
x = 30/3
x = 10
