Answer:10times
Step-by-step explanation:
-x+y=-3, 3x+2y=9
1. multiply the first row by the second
-2x+2y=-6, 3x+2y=9
2. subtract the second row from the first row
-5x=-15
3. sole for x in the above equation
x=-15/-5
x=15/5
x=3
4. substitue x=3 into -2x+2y=-6
-2*3+2y=-6
5. solve for y in the above equation
-6+2y=-6
2y-6=-6
2y=0
y=0
6 therefore,
x=3 and y=0
Have a nice day :D
Answer:
x=m-a/12
the m-a should be over 12 as the numerator but it's hard to type it like that
Step-by-step explanation:
a+12x=m
12x=m-a
x=m-a/12
Left side is 22.
22 x 10 = 220
(20 - 6) x 12 = 168
6 x 20 = 120
220 + 168 + 120 = 508
Thank you very much.
