Answer:
x = 2
Step-by-step explanation:
3(5x + 2) = 8x + 20
open the parenthesis
15x + 6 = 8x + 20
subtract 8x from both sides of the equation
15x - 8x + 6 = 8x - 8x + 20
7x + 6 = 20
subtract 6 from both sides of the equation
7x + 6 - 6 = 20 - 6
7x = 20 - 6
7x = 14
divide both sides of the equation by 7
7x/7 = 14/7
x = 14/7
x=2
3(5x+2)=8x+20
First, we distribute the 3.
15x+6=8x+20
Now we can subtract 8x from both sides of the equation.
7x+6=20
Next, we subtract 6 from both sides.
7x=14
Finally, we divide both sides by 7.
