Answer:
x=5 y=-1
Step-by-step explanation:
7x-2y=37
[2(4x+y=19)]=
8x+2y=38
---------------------
15x/15=75/15
x=5
[4(5)+y=19]
y=-1
Answer:
5 times 12 = 12 times 5
Step-by-step explanation:
You flipped the factors since they were the same. 5 times 12 = 60 when you flip the factors 12 times 5 = 60
Answer:
x = (-10)/43
Step-by-step explanation:
Solve for x:
91 x = 5 x - 20
Subtract 5 x from both sides:
91 x - 5 x = (5 x - 5 x) - 20
91 x - 5 x = 86 x:
86 x = (5 x - 5 x) - 20
5 x - 5 x = 0:
86 x = -20
Divide both sides of 86 x = -20 by 86:
(86 x)/86 = (-20)/86
86/86 = 1:
x = (-20)/86
The gcd of -20 and 86 is 2, so (-20)/86 = (2 (-10))/(2×43) = 2/2×(-10)/43 = (-10)/43:
Answer: x = (-10)/43

Step-by-step explanation:
Since they have the same denominator you can easily add them together.
5 2/5 + 2 3/5 =
( 5 + 2) + 2/5 + 3/5
7 + 2/5 + 3/5
7 + 1
