Explicación paso a paso:
1) 9÷(-3)+3x = -24+30÷(-10)
-3+3x = -24+(-3)
-3+3x = -24-3
3x = -24
x = -8
2) -2x+28÷(-2) = -2×8
-2x-14 = -16
-14+16 = 2x
2 = 2x
1 = x
3) -2(x+1)+8÷(-2) = -10÷(-2)+1
-2x-2-4 = 5+1
-2x-6 = 6
-6-6 = 2x
-12 = 2x
-6 = x
4) (x+1)+16÷4 = 25÷5-(-7)
x+1+4 = 5+7
x+5 = 12
x = 7
5) 3(x²+5)+20 = -31(-2)
3x²+15+20 = 62
3x² = 62-35
3x² = 27
x² = 9
x = 3
6) 5(√x)+3 = -5(-9)+3(-1)²
5(√x)+3 = 45+3
5(√x)+3 = 48
5(√x) = 45
√x = 9
