6x - 3
3x + 6
enter your answer in the box.
the numbers are 42 and 49
let's make it into a simple equation. make the ratios into a single variable like this: 6x+7x=91. if you simplify it more you would get 13x=91. from here divide both sides by 13. this will result with x being 7. but the problem wants you to find 6x and 7x. if you multiply 7 with 6 you would have an answer of 42. if you multiply 7 with 7 you get 49. if you want to check add 42 and 49. if you get 91, this means that the answer is correct
factor 6mn ( greatest common factor) out of the 3 terms:
6mn(4m) + 6mn(5n) + 6mn(3)
factor 6mn out of the first 2 terms:
6mn(4m + 5n +3)
given matrix allows you to write that
let from the last equation,
from the first equation,
then the solution of the system has form
where t is any real number.
