ANSWER:-

x= $\frac{ - 13}{10}$

According to question:-

$2x + 3y = 4$

$5y = 11$

$y = \frac{11}{5}$

Putting the value of y in the equation:-

$2x + 3 \times \frac{11}{5} = 4$

$\frac{2x}{1} + \frac{33}{5} = 4$

$= \frac{10x + 33}{5} = 4$

$10x + 33 = 4 \times 5$

$10x + 33 = 20$

$10x = 20 - 33$

$10x = - 13$

$x = \frac{ - 13}{10}$

Check

$2 \times \frac{ - 13}{10} + 3 \times \frac{11}{5}$

$= \frac{ - 13}{5} + \frac{33}{5}$

$= \frac{ - 13 + 33}{5}$

$= \frac{20}{5}$

$= 4$
