Question

8. Solve for x and y :

2x+ 3y= 17

2x + 2– 3y+1= 5

Answer 1

⭐⭐Hello friend..Ur answer is here⤵⤵

⚫ 2x+3y=17.......equation 1

2x+2-3y+1=5

2x-3y=2.....equation 2

Solving equation 1 and 2 we get

➡ 4x=19

➡ x=19/4

2x+3y=17

2×19/4+3y=17

➡3y=17-19/2

➡ 3y=15/2

➡ y=5/2

➡ So x=19/4 and y=5/2

I HOPE IT IS HELPFUL TO YOU ☺

Answer 2

Answer:

x = 3 and y = 2

Given: $2^{x} + 3^{y} = 17 , 2^{x+2} - 3^{y+1} = 5$

By observation we an assume that x = 3 and y = 2

⇒ $2^{3} + 3^{2} = 17\\and\ \\2^{5} - 3^{3} = 32 - 27 = 5$

∴ x = 3 and y = 2
