Step-by-step explanation:
2x + 2y = -2.............equation 1
3x - 2y = 12..............equation 2
Solving both equations we get
2x + 2y = -2
<u>3x </u><u>-</u><u> </u><u>2y </u><u>=</u><u> </u><u>1</u><u>2</u>
5x = 10
Therefore x = 2
Now putting x = 2 in equation 1
2 * 2 + 2y = -2
4 + 2y = -2
2y = -2 -4
2y = -6
Therefore y = -3
Here you go! HOPE THIS HELPED
Answer:
16x -12y = 4
15x +12y = 27
Step-by-step explanation:
4x-3y = 1
5x+4y=9
Multiply the first equation by 4
16x -12y = 4
Multiply the second equation by 3
15x +12y = 27
48x² + 8 = 8(6x² + 1) [we factor out 8, because 48 and 8 are divisible by 8]
