The LCD of 3 and 4 is 12. To make 4 into 12, we multiply it by three, so 3 would also have to be multiply by 3, turning 3/4 into 9/12.
The same thing applies to 1/3, only it needs to be multiplied by 4. So it would become 4/12
9/12 - 4/12 = 5/12
Subtract 25 from each side of that equation, and it says that x-squared = negative 25. 'X' can't be any real number. If you know how to work with imaginary numbers, you'll know that the two solutions are x=5i and x=-5i ... the ' i ' is the symbol meaning the square root of -1 .
Answer:
1,1
Step-by-step explanation:
Substitute 1 and 1 for x and y
x + y = 2
(1) + (1) = 2 ----> Works
x + 3y = 4
(1) + 3(1) = 4
1 + 3 = 4 ------> Works
