Answer:


\sf \: x = 5

Explanation:

Given equation,

→ y = 4x - 2

Now we have to use,

y = 18

Then the value of x will be,

→ y = 4x - 2

→ 18 = 4x - 2

→ 18 + 2 = 4x

→ 20 = 4x

→ 4x = 20

→ x = 20 ÷ 4

→ [ x = 5 ]

Hence, the value of x is 5.

\huge\text{Hey there!}



\mathsf{y = 4x - 2}\\\mathsf{18 = 4x - 2}\\\mathsf{4x - 2 = 18}\\\large\textbf{ADD 2 to both sides:}\\\mathsf{4x - 2 + 2 = 18 + 2}\\\large\textbf{Simplify it:}\\\mathsf{4x = 18 + 2}\\\mathsf{4x = 20}\\\large\textbf{Divide 4 to both sides:}\\\mathsf{\frac{4x}4{} = (20)/(4)}\\\large\textbf{Simplify it:}\\\mathsf{x = (20)/(4)}\\\mathsf{x = 5}



\huge\text{Therefore, your answer should be:}


\huge\boxed{\mathsf{x = 5}}\huge\checkmark
