Answer:

x = -9.6

Step-by-step explanation:

First you the distributive property. -4(5x)=-20x and -4(-1)=4. Now we have -20x + 4 = 196. To single out the variable we subtract 4 from both sides. 4 - 4 = 0 and 196 - 4 = 192, now we have -20x = 192. Finally divide by -20 on both sides, -20 ÷ -20 = 1, 1x is the same as x. 192 ÷ -20 = -9.6. There your have it.

-4(5x - 1)= 196, x = -9.6.
