Question

(2x+3, 3y-7)=(7,8) find value of x and y​

Answer 1

Answer:

2x+3=7

2x=7-3=4

2x=4

x=2

3y-7=8

3y=8+7

3y=15y=15

Answer 2

Answer:

x = 2 & y = 5

Step-by-step explanation:

When (a, b) = (c, d), it is possible only when a = c and b = d. So, here,

=> (2x+3, 3y-7) = (7,8)

=> 2x+3 = 7 & 3y-7 = 8

=> 2x = 7-3 & 3y = 8 + 7

=> 2x = 4 & 3y = 15

=> x = 4/2 & y = 15/3

=> x = 2 & y = 5
