Answer:

x=3

Step-by-step explanation:

4(2x - 1) = 20

Divide each side by 4

4/4(2x - 1) = 20/4

2x-1 = 5

Add 1 to each side

2x-1 +1 = 5+1

2x= 6

Divide by 2

2x/2 = 6/2

x = 3

Answer:

[tex]x=3[/tex]

Step-by-step explanation:

Use the distributive property to expand the left side:

[tex]a(b-c)\\\\ab-ac[/tex]

Simplify:

[tex]4(2x-1)=20\\\\4(2x)-4(1)=20\\\\8x-4=20[/tex]

Isolate the variable, x. Add 4 to both sides of the equation:

[tex]8x-4+4=20+4\\\\8x=24[/tex]

Now divide both sides by 8:

[tex]\frac{8x}{8} =\frac{24}{8}\\\\ x=3[/tex]

The value of x is 3.
