Question

Solve the following pairs of equations:
x+y = 3.3
0.6/3x-2y
also,3x-2y is not equal to 0
​

Answer 1

x+y=3.3 _(1)

0.6/3x-2y=0

3x-2y=0×0.6

3x-2y=0 (2)

from eqn (2)

3x-2y=0

3x=2y

x=2y/3 (3)

replace x in equation (1)

2y÷3+y=3.3

2y+y=3.3×3

3y=3.3×3

y=3.3×3/3

y=3.3

replace y in equation (1)

x+3.3=3.3

x=3.3-3.3

x=0

x= 0,y=3.3
