5) 2.4×10^-5 / 4.5×10^-11

2.4×10^-5= 0.000024
4.5×10^-11= 0.000000000045

=0.000024/0.000000000045

=24/1 × 1,000,000/45

=24,000,000/45

=533,333.33°

2x + 3 = 5x - 2

2x - 5x = - 2 - 3
-3x = -5
x = -5/-3
x = 1.66°

6x + 4 = 6x + 4

6x - 6x = 4 - 4
0x = 0

2 (2x + 3) = 8x - 2

4x + 6 = 8x - 2
4x - 8x = -2 - 6
-4x = -8
x = -8/-4
x = 2

-3x + 2 = -3x + 5

-3x + 3x = 5 - 2
0x = 3

Letter be has no solution because it is broken down as "0x = 0"

Mixed equations. Show work please

Alex_Xolod [135]

Solving:

1)

-58 - 6x = 42 + 4x
Pass the numbers with letter to the left and the numbers without letter to the right, changing the signal as they change sides.
- 6x - 4x = 42 + 58
- 10x = 100 simplify by (-1)
10x = - 100
 $x = \frac{-100}{10}$
$\boxed{x = - 10}$ 

2)

37 + 5x = -2x - 33
Pass the numbers with letter to the left and the numbers without letter to the right, changing the signal as they change sides.
5x + 2x = - 33 - 37
7x = - 70
 $x = \frac{-70}{7}$
$\boxed{x = - 10}$

3)

27 - 9x = -6x - 39
Pass the numbers with letter to the left and the numbers without letter to the right, changing the signal as they change sides.
- 9x + 6x = - 39 - 27
- 3x = - 66 simplify by (-1)
3x = 66
$x = \frac{66}{3}$
$\boxed{x = 22}$
