Question

b)
7(y + 3) - 2 (x + 2) = 14;
4(y-2) + 3(x - 3)=2​

Answer 1

Answer:

Step-by-step explanation:

7y+21-2x+4=14

7y+21-2x=10

7y-2x=-11 ----->eq 1

4y-8+3x-9=2

4y+3x=19 ------>eq 2

4(eq 1) and 7(eq 2)

28y-8x=-44 ------->eq 3

28y+21x=133 ------->eq 4

Subtract eq 3 and 4 then the value after subtraction is

-13x=-177

x=13.6153846154
