To solve for $x$, set $y_1 = y_2$: $\frac{x + 6}{5} = \frac{x + 8}{7}$. Cross-multiply to get $7(x + 6) = 5(x + 8)$. Simplify to $7x + 42 = 5x + 40$. Solve for $x$ to get $x = -1$.

Solve the Equation y1=x+65,y2=x+87y _ { 1 } = \frac { x + 6 } { 5 } , y _ { 2 } = \frac { x + 8 } { 7 }y1​=5x+6​,y2​=7x+8​

Solve the Equation $y _ { 1 } = \frac { x + 6 } { 5 } , y _ { 2 } = \frac { x + 8 } { 7 }$
