Question

Solve the equation 7x=3^2-1

Answer 1

`\huge\text{Hey there!}`

`\huge\textbf{Equation:}`

`\mathsf{7x = 3^2 - 1}`

`\huge\textbf{Simplifying:}`

`\mathsf{7x = 3^2 - 1}`

`\mathsf{3^2 - 1 = 7x}`

`\mathsf{3*3 - 1 = 7x}`

`\mathsf{9 - 1 = 7x}`

`\mathsf{8 = 7x}`

`\huge\textbf{Divide \boxed{7} to both sides:}`

`\mathsf{(7x)/(7) = (8)/(7)}`

`\huge\textbf{Simplify it:}`

`\mathsf{x = (8)/(7)}`

`\mathsf{x \approx 1 (1)/(7)}`

`\huge\textbf{Therefore, your answer should be:}`

`\huge\boxed{\mathsf{x = (8)/(7)}}\huge\checkmark`
