Question

2 x + 3 y = 29 and 2 x +5 y =42 by elimination​

Answer 1

Answer:

Step-by-step explanation:

2x+3y=29

2x=29-3y

x=(29-3y)/2-------(1)

put (1) in another equation given

2{(29-3y)/2}+5y=42

29-3y+5y=42

29+2y=42

(42-29)/2=y

13/2=y

6.5=y

put y=6.5 in (1)

x=[29-3(6.5)]/2

x=(29-19.5)/2

x=9.5/2

x=4.75

therefore x=4.75

               y=6.5
