Just use quiz lit and it’ll give you all the answers you need for your answers. Ok. Just
2(x-y) - 3(x-2y) = 0
2(x) - 2(y) -3(x) -3(-2y) = 0
2x - 2y - 3x + 6y = 0
-x + 4y = 0
Value of x:
-x = -4y
-x / -1 = -4y / -1
x = 4y
Value of y:
-x + 4y = 0
4y = x
4y / 4 = x / 4
y = x/4
Answer: 15 + 53/77
Step-by-step explanation:
Multiplying a fraction by 1 does not change the value.
Any number divided by itself is 1.
For instance, 11/11 = 7/7 = 1.
12 + 1/7 + 3 + 6/11 = 15 + 1/7 + 6/11
= 15 + (11×1)/(11×7) + (7×6)/(7×11)
= 15 + 11/77 + (6×7)/77
= 15 + (11 + 6×7)/77
= 15 + 53/77
It is faster to make sure to multiply by the "smallest" form of one that will work, but you don't have to. You only need to make sure that at the end there are no common factors in numerator and denominator, and that numerator is smaller than denominator.
The answer is 21 because I added 8 + 10+3=and I got 21
