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.
