To solve the equation, cross-multiply to get $9(x + 7) = 8(x + 8)$. Simplifying both sides gives $9x + 63 = 8x + 64$. Subtract $8x$ from both sides to get $x + 63 = 64$. Subtract 63 from both sides to find $x = 1$.

Solve the Equation x+78=x+89\frac { x + 7 } { 8 } = \frac { x + 8 } { 9 }8x+7​=9x+8​

Solve the Equation $\frac { x + 7 } { 8 } = \frac { x + 8 } { 9 }$
