Question

7(3-2y) - 15y = 2
.. 21 - 14y - 15y = 2
:.-29 y = - 19
..y = 19/20
Substituting the value of y in equation (3).
x = 3 -2 (19/29) = 49/29 (how 3-2(19/29)=49/29) details please​

Answer 1

Answer:

y=19/29

X=3-2*19/29. (19*2=38)

X=3-38/29. now take LCM

X=(87-38)/29. 29*3=87

X=49/29

Answer 2

Answer:

3-2(19/29)=49/29

Step-by-step explanation:

=3-2*19/29

=3-38/29

(now take LCM)

=87-38/29

=49/29
