Question

Solve the following simultaneous linear equations:

3x + 4y = 11

4x + 3y = 10​

Answer 1

Answer:

3x+4y=11 multiply this equation by 4

4×+3y=10 multiply this equation by 3

Step-by-step explanation:

12x+16y=44

12x+9y=20

_________

7y= 14 ( 12 x and 12 x will be cancelled )

y=14/7

y =2

put value of y in equation 2

3x+4×2=11

3x+8=11

3x+3

x=3/3

x=1

x_y=1_2

x_y=_1

Answer 2

Answer:

Step-by-step explanation:

3x+4y=11

3x-11=4y

3x-11/4=y

4x+3y=10

4x+3*(3x-11)/4=10

4x+9x-33/4=10

16x+9x-33/4=10

25x-33=40

x=73/25

4*73/25+3y=10

292/25+3y=10

292/25-10=3y

292-250/25=3y

42/25=3y

42=75y

y=42/75
