Answer» ANSWER: X + y = 14 x = 14 - y substituting x = 14 - y in equation x-y =14 (14 - y ) - y = 14 14-y -y = 4 14 - 2y = 4 y = 10 / 2 y = 5 Step-by-step explanation: plzz mark me brilliant

Solve the following pairs of linear equation by substitution methoda) x + y = 14X - y = 4Ans:-b) 3x - y - 3 = 0X - 3y – 9 = 0Ans;

Answer»

ANSWER:

X + y = 14

x = 14 - y

substituting x = 14 - y in equation

x-y =14

(14 - y ) - y = 14

14-y -y = 4

14 - 2y = 4

y = 10 / 2

y = 5
