Solve the pair of simultaneous equation 4x+6y=21 and 7x-3y=3

X=1.5, y=2.5

Step-by-step explanation:

By elimination method

U have to make either x or y values equal and then eliminate it

The y values have a common value 12

By multiplying 6*2 and 3*4

2 (4x+6y) = (21) 2

4 (7x-3y) = (3) 4

8x+12y=42

+

28x-12y=12

36x=54

X=54/36=1.5

Substitute x with 1.5

Y=2.5
