Question

x3 +5y =13:2 +y2=19find out answer

​

Answer 1

∴x=9,y=2

Step-by-step explanation:

+5y=13

2x+ 2y =19

Multiplying equation (i) by 3 and equation (ii) by 2. we get,

x+15y=39

4x+y=38

To make the coefficients of x equal multiplying equation (iii) by 4. we get ,

4x+60y=156

Subtract equation (iii) from equation (iv). we get,

4x+60y−(4x+y)=156−38

59y=118⇒y=2

Substitute y=2 in equation (iii). we get,

x+15(2)=39⇒x=9

∴x=9,y=2
