Question

3x+2y=11 and 2x+3y =4 solve the linear equation in two variable by substitution method

Answer 1

Answer:

x=5,y=-2

Step-by-step explanation:

3x+2y=11      ................ (1)

2x+3y=4      ................. (2)

Resolving eq(1):

3x+2y=11

3x=11-2y

x=(11-2y)/3    ................ (3)

Substituting value of x in eq(2):

2(11-2y/3)+3y=4

(22-4y)/3+3y=4

(22-4y+9y)/3=4

Multiplying both sides by 3,

22-4y+9y=12

22+5y=12

Subtracting both sides by 22,

5y=-10

Dividing both sides by 5,

y=-2

Subtituting the value of y in eq(1)

3x+2y=11

3x+2(-2)=11

3x-4=11

Adding 4 on both sides,

3x=15

Dividing by three on both sides,

x=5
