Question

If x is equal to 2 k - 1 and Y is equal to K is a solution of the equation 3 x minus 5 Y - 7 is equal to zero find the value

Answer 1

Step-by-step explanation:

x=2k-1

Y=k

Given 3x-5Y-7=0

Substituting the values of x and Y int he equation

3(2k-1)-5k-7=0

6k-3-5k-7=0

k-10=0

k=10

Therefore Y=10 (k=Y)

x=2k-1

=2(10)-1

=20-1

x=19
