Question

3(2u+v)=7uv
3(u+3v)=11uv​

Answer 1

Answer:

u = 1

v = 3/2

Step-by-step explanation:

6u + 3v =7uv ----- 1

(3u + 9v = 11uv)×2 -------- 2

subtracting equation 1 from equation 2

6u + 18v = 22uv

-(6u +3v) = -7uv

6u + 18v = 22uv

-6u - 3v = -7uv

____________

0 + 15v = 15uv

15v÷ 15v = u

u =1

put u in equation 1

6(1) +3v = 7(1)(v)

6 =7v - 3v

6 = 4v

6/4 = v

3/2 = v
