Question

solve by substitution method 2X-3y / 4 = 3​

Answer 1

Answer:

2x−3y/ 4=3…..(i) 5x=2y+7……..(ii) Onmultiplying(i)by2and(ii)by3/4,weget: 4x−3/2y=6…...(iii) 15/4x=3/2y+21/4….(iv) Onsubtracting(iii)and(iv),weget: −1/4x=−3/4 ⇒x=3 Onsubstitutingx=3in(i),weget: 2×3−3y/4 =3 ⇒3y/4 =(6–3)=3 ⇒y=(3×4)/3=4 Hence,thesolutionisx=3andy=4.
