Question

1) Express X in terms of Y for the linear equ-
ation 2/3X + 4Y = -7
2) if the length of a rectangle is decreased by
3 unit and breadth increased by 4 unit
then the area will increase by 9 unit represent this equation as a linear equation in two variable.

​

Answer 1

Answer:

2/3x+4y=-81

Step-by-step explanation:

we consider-

length =x&

breadth=y

x+3+y+4=-63

2/3x+2+4y+16=-63

2/3x+4y+18=-63

2/3x+4y=-63-18

2/3x+4y=-81
