I’m a 10th grade geometry student and I can’t figure these out and these are due by noon tomorrow, please help me out I need help

Answer 1

See the explanation below.

Explanation:

17) 40=x+45

x = -5

18) 70 = -2 + 8x

72 = 8x

x = 9

19) 19x - 3 = 17x + 11

2x = 14

x = 7

20) -2 + 14x = 12x + 14

2x = 16

x = 8

21) 11x - 3 + 18x + 9 = 180

29x + 6 = 180

29x = 174

x = 6

22) 6x - 4 + 14x + 4 = 180

20x = 180

x = 9

23) 68 + x + x + 128 = 180

196 + 2x = 180

2x = -16

x = -8

24) x + 87 + x + 107 = 180

2x + 194 = 180

2x = -14

x = -7

25) 70 + 12x - 10 = 180

60 + 12x = 180

12x = 120

x = 10
