Answer: x=-0.4 or -2/5

Step-by-step explanation:

Distribute: 4 (-3x-1)=13x+6

Add 4: -12x-4=13x+6

Subtract -13x: -12x=13x+10

Divide by -25: -25x=10

x= 2/5

x=-0.4

Hope this helps ma dude!!

Answer:

x=-2/5

Step-by-step explanation:

4(-3x-1)=13x+6 ~ Distribute the 4 into the parenthesis

-12x-4 = 13x+6 ~ add 12x to both sides

-4= 25x + 6 ~ subtract 6 from both sides

-10 =25x ~ divide by 25

-10/25 = x ~ simplify the fraction by dividing the num. and den by 5

-2/5 =x
