Answer:

X= -3

Step-by-step explanation:

Hope this helps.!     tep 1: Simplify both sides of the equation.

2(10x+8)−1=5(x−6)

(2)(10x)+(2)(8)+−1=(5)(x)+(5)(−6)(Distribute)

20x+16+−1=5x+−30

(20x)+(16+−1)=5x−30(Combine Like Terms)

20x+15=5x−30

20x+15=5x−30

Step 2: Subtract 5x from both sides.

20x+15−5x=5x−30−5x

15x+15−15=−30−15

15x=−45

Step 4: Divide both sides by 15.

15x

15

=

−45

15

x=−3

15x+15=−30

Step 3: Subtract 15 from both sides.  ITs X= -3
