Answer:

1) x=3

2)x=8

3)x=-6

4)x= 1/3

5)x=16/3

Step-by-step explanation:

I don't know if that a exponent but I took it as an whole number and I don't know how to explain this so here's the solution

1. -5x+4x=-3

-x=-3

x=3

2. 2x +3x-40=0

5x-40=0

5x=40

x= 8

3. 6x-7x-6=0

-x-6=0

-x= 6

x=-6

4. 4x+5-3=0

9x-3=0

9x=3

x=1/3

5.2x+4x=32

6x=32

x=16/3

Answer:

1. x1 = 1, x2 = 3/2
2. x1 = -8 , x2 = 5
3. x1 = -⅔ , x2 = 3
4. x1 = -3 , x2 = ½
5. x1 = -8 , x2 = 4
