These are the first 7 multiple of 3
0,3,6,9,12,15,18,21
Rearrange the first equation2x + y = 20take away 2x from both sidesy = 20 - 2x substitute this y value into the second equation6x - 5(20 - 2x) = 126x -100 +10x = 12add 100 to both sides6x + 10x = 11216x = 112divide both sides by 16 x = 7Substitute this x value into the first equation to get y.2(7) + y = 2014 + y = 20take away 14 from both sidesy = 6
So, y = 6 and x = 7
4/5 divided by 2/1 is 2/5.
Answer:
Step-by-step explanation:
2x-6=3-x
+x on both sides
3x-6=3
+6 on both sides
3x=9
/3 on each side
x=3
