0.9x+20=830
x=

Answer 1

To solve the equation 0.9(x−20)=830 for x, distribute 0.9 to both terms inside the parentheses, then solve the resulting equation.

Step-by-step explanation:

To solve the equation 0.9(x−20)=830 for x, we can start by distributing 0.9 to both terms inside the parentheses:

0.9x - 18 = 830

Next, we can add 18 to both sides of the equation to isolate the variable:

0.9x = 848

Finally, we can divide both sides of the equation by 0.9 to solve for x:

x = 848 ÷ 0.9 = 942.22
