1). solve x/5=-6 2). 5c+4=19. 3). 3a=12. factorise fully 4t-20

Question

please solve, just to confirm i'm working out correctly

Answer 1

x/5 = -6

1). x = -6 * 5

x = -30

2). 5c + 4 = 19

5c = 15

c = 3

3). 3a= 12

a = 4

4). 4t - 20

4(t - 5)

Answer 2

x/5-6=-2;x=20

Answer 3

-6=x/2-7x=-2

Answer 4

How to solve for x in this equation 4 to the power of 3x= 8 to the power of 5x-4 and aslo this equation (0.008) To the power X= 1/ 25 and also this equation 2 to the power of negative 2x =1/25 Please can I have the steps of solving for X in all of these equations

Answer 5

250 mg/1 ml = x\5 ml
