Question

Find the linear equation by substituting or by cross multipication methods.
1 .....88+ 5y = 9
3x +2y = 4
2......4x-3y=23
3x+4y=11
​

Answer 1

Answer:-(Using substitution method).

1) 88x+5y=9------1

3x+2y=4------2

From equation-2

→3x=4-2y

→x=4-2y/3

Substitute value of 'x' in eq-1

→88(4-2y/3)+5y=9

→352-176y+15y=27

→352-161y=27

→ -161y=-325

→ y= 325/161

→ y=2.01
