Answer:
x = -2
y = 1
Step-by-step explanation:
x−2y=6
<em>Multiply both sides by 2</em>
x-4y=12
<em>Subtract x from both sides</em>
-4y=12-x
2x−4y=10
<em>Subtract 2x from both sides</em>
-4y=10-2x
Put the 2 equations together:
12-x=10-2x
<em>Add x to both sides</em>
12=10-x
<em>Subtract 10 from both sides</em>
2= -x
<em>Multiply both sides by -1</em>
x= -2
x−2y=6
<em>Multiply both sides by 2</em>
2x-2y=12
<em>Add 2y to both sides</em>
2x=12+2y
2x−4y=10
<em>Add 4y to both sides</em>
2x=10+4y
x−2y=6
<em>Multiply both sides by 2</em>
2x-2y=12
<em>Add 2y to both sides</em>
2x=12+2y
2x−4y=10
<em>Add 4y to both sides</em>
2x=10+4y
Put the 2 equations together:
12+2y=10+4y
<em>Subtract 10 from both sides</em>
2+2y=4y
<em>Subtract 2y from both sides</em>
2=2y
y=1
Answer:
(5a - 8) + (2a² + 2a − 1) = 2a² + 7a - 9 - <u>correct.</u>
Step-by-step explanation:
(5a - 8) + (2a² + 2a − 1) = 2a² + 7a - 9 - <u>correct;</u>
(6² +6b-4) (3b +6²) = 26² +36-4 - incorrect (correct is: 18b²+...36²);
(9c-4c²) - (2c² + c) = -6c² + 10c - incorrect (correct is: -6c² + 8c).
