x -3y = 4 multiplie both sides by -2 => -2x +6y = -8
2x +Qy = 8
-2x +6y = -8
2x +Qy = 8
------------------ assume the same terms
0 6y +Qy = 0
6y +Qy = 0
Qy = -6y divide both sides by y and will get
Q = -6
Answer:
6 : 16, 12 : 32 and 18 : 48.
Step-by-step explanation:
Answer:
a simplified fraction
Step-by-step explanation:
3 -

=

- 7
First, simplify

to

/ Your problem should look like: 3 -

=

- 7
Second, simplify

to

/ Your problem should look like: 3 -

=

- 7
Third, multiply both sides by 9 (the LCD of 9,3). / Your problem should look like: 27 - 2b = 3b - 63
Fourth, add 2b to both sides. / Your problem should look like: 27 = 3b - 63 + 2b
Fifth, simplify 3b - 63 + 2b to 5b - 63. / Your problem should look like: 27 = 5b - 63
Sixth, add 63 to both sides. / Your problem should look like: 27 + 63 = 5b
Seventh, simplify 27 + 63 to 90. / Your problem should look like: 90 = 5b
Eighth, divide both sides by 5. / Your problem should look like:

= b
Ninth, simplify

to 18. / Your problem should look like: 18 = b
Tenth, switch sides. Your problem should look like: b = 18
Answer:
b = 18
