Answer:
31/9
Explanation:
Given the equation
[tex]2\mleft(5x-20\mright)-15+8x=7[/tex]Step 1: Open the brackets
[tex]10x-40-15+8x=7[/tex]Step 2: Take all constants to the right-hand side.
[tex]\begin{gathered} 10x+8x=7+40+15 \\ 18x=62 \end{gathered}[/tex]Step 3: Divide both sides of the equation by 18
[tex]\begin{gathered} \frac{18x}{18}=\frac{62}{18} \\ x=\frac{62}{18} \\ x=\frac{31}{9} \end{gathered}[/tex]The value of x that satisfies the given equation is 31/9.
