Solve for y
eliminate x
multiply firs tequation by -5 and 2nd by 3 and add them
-15x-30y=-15
<u>15x-3y=81 +</u>
0x-33y=66
-33y=66
divide both sides by -33
y=-2
the y coordinate is y=-2
Answer:
This is your answer. thanks!!
Correct Question :-
- If y = - 7 & x = - 21 , determine x when y = 9
Given :-
We need to find :-
Solution :-
Using proportion ,
By means & extremes ,
=> - 7x = - 21 × 9
=> x = ( - 21 × 9 ) / - 7
=> x = 3 × 9
=> x = 27
Hence , when y = 9 → x = 27
Answer:
x+6y=150
Step-by-step explanation:
If you add 6y to both sides of the equation, it becomes this, making it equal.
Answer:
Step-by-step explanation:
x must be an even number from 0 to 9. So x can be
0 2 4 6 8
