Explicación paso a paso:
a) -7n+45 = -5n+15
- 7n + 5n = 15 - 45
- 2n = - 30
n = -30/-2
n = 15
b) 92+3x=5x+100
3x - 5x = 100 - 92
- 2x = 8
x = 8/-2
x = - 4
c) -5y+85=2y+15
-5y + 2y = 15 -85
-3y = - 70
y = -70 / -3
y = 23,3
d) 2(h3)=8
6h = 8
h = 8 / 6
h= 4 / 3
e) 2(4x-5)=30
8x - 10 = 30
8x = 30 + 10
x = 40/8
x = 5
f) 5(x+1)=2(2x+4)
5x + 5 = 4x + 8
5x - 4x = 8 - 5
x = 3
g) 6(x+4)=8(x+10)
6x + 24 = 8x + 80
6x - 8x = 80 - 24
- 2x = 56
x = 56 / -2
x = - 28
