Question

2) Solve: 3x - Y+7 +2=10; 3y +*+11 = 14
11​

Answer 1

Answer:

9x

Step-by-step explanation:

3x-y+7+2=10. .....1. 3y+. +11=14. ........2

3x-y+9=10

3x-y=10-9

3x-y=1

y=1-3x

put this as eq 3

from eq 2 we get

In the vacant place take one variable as A

so,

3y+A+11=14

from eq 3

3y+A=14-11

3(1-3x)+A=3

3-9x+A=3

A=3-3+9x

A=9x
