Best Answer

15x+7y = 4

5x+7y = 2

Subtract the bottom equation from the top equation to eliminate y which will leave you with:

10x = 2

Divide both sides by 10 to find the value of x:

x = 2/10 = 1/5 in its lowest terms.

Substitute the value of x into the original equations to find the value of y:

Therefore: x = 1/5 and y = 1/7
