Question 34: Find y know \(\frac{7}{{3 + 4y}} = \frac{{ – 2}}{9}\)

\(\begin{aligned} &\frac{7}{{3 + 4y}} = \frac{{ – 2}}{9}\\ & – 2\left( {3 + 4y} \right) = 7.9 \\ & – 2\left( {3 + 4y} \right) = 63\\ &3 + 4y = -\frac{{63}}{2}\\ &4y =- \frac{{63}}{2} – 3\\ &4y =- \frac{{69}}{2}\\ &y =- \frac{{69}}{2}:4\\ &y =- \frac{{69}}{8} \ end{aligned}\)
