Answer:
x = 3 ; y = 2
Explanation
3x - y = 7
= 3x - y - 7 = 0
= 3x - 7 = y — (equation i)
Substitute (equation i) into the second equation:
3x + (3x - 7) = 11
Expand the brackets by applying the Distributive Law and bring all the like terms together:
3x + 3x - 7 = 11
= 6x - 7 = 11
= 6x = 11 + 7
= 6x = 18
= x =
= x = 3
Substitute the calculated value of x into (equation i) to determine the value of y:
3 x - 7 = y
= 3(3) - 7 = y
= 9 - 7 = y
= y = 2
