Answer:
For all real numbers a except 0, we have
a(1/a) = 1
Step-by-step explanation:
Multiplication of real numbers are having the following properties:
i) commutative = ab = ba
ii) associative a(b+c) =ab+ac
iii) Multiplicative identity element exists such that for any number
a*1 =1*a = a
i.e. 1 is identity.
Inverse property is for any a not equal to 0, we have a real number such that
a*that real number = multiplicative identity
i,.e. a(a real number) = 1, a not equal to 0
In other words, there exists an 1/a for all a not equal to 0 satisfying a*1/a = 1
Answer:
(x, y) = (-4, 15)
Step-by-step explanation:
The two equations have the same coefficient for y, so you can eliminate y by subtracting one equation from the other. Here the x coefficient is largest for the first equation, so it will work best to subtract the second equation.
(3x +y) -(2x +y) = (3) -(7)
x = -4 . . . . . . . . simplify
Now, we can find y by substituting this value for x.
2(-4) +y = 7
y = 7 +8 = 15 . . . . . add 8 to both sides of the equation
The solution is (x, y) = (-4, 15).
(8y + 17) = (6x - 7)
(3x -29) + (6x -7) = 180
9x -36 = 180
9x = 216
x = 24
(8y + 17) = (6x - 7)
8y + 17 = 6(24) - 7
8y + 17 = 144 -7
8y = 120
y = 15
I hope this helps!! (and hope it’s correct hahah :))
