Answer 2

２x - ３y = ７ ------(a)

３x + ２y = ４------(b)

multiple 3 in equ. (a), we get

➔ ６x - ９y = ２１----(a)

➔ ６x + ４y = ８----(b)

Substrate equ. (b) from equ. (a), we get

➔ - 13 y = 13

➔ y = $\bf{\dfrac{13}{-13}}$

➔ y = $\bf\red{-1}$

Substitute the above value in equ. (b), we get

➔ 6x + 4 × (-1) = 8

➔ 6x - 4 = 8

➔ 6x = 12

➔ x = $\bf\red{2}$
