Use cross multiplication so you have
7/x = 2/4
multiple 7 and 4 to get 28 and multiply x and 2 to get 2x and set them equal to each other
so your new equation is 2x=28 and then you just need to solve for x
The answer is x=14
Answer:
Step-by-step explanation:
times p on both sides
then plus e on both sides
then divide t on both sides
Matrix :
1 4 4
5 2 2
1 5 5
=> Determinant =
1 * (2*5 - 2*5) - 4 * (5*5 - 1*2) + 4 * ( 5*5 - 2*1)
= 1*(10 - 10) - 4*(25 - 2) + 4*(25 -2) = 1*0 + 4* 23 + 4*(25 - 2) = 0 - 4*23 + 4*23 = 0
