Question

Solve : 4x +
= 15 and 3x - = 7.
Hence, find 'a' if y = ax - 2.​

Answer 1

wrong question .........

Answer 2

Step-by-step explanation:

given that

4x+y=15 ..... (i)

3×-y=7 ..... (ii)

y=ax-2 ..... (iii)

now we add eqn (i) and (ii)we get,

7x=22

x= 22/7 ... (iv)

put this value of x in eqn (ii) we get

y=3 (22/7) -7

y=19/7 ... (v)

from the eqn (iv) and (v) we put the value of x and y in eqn (iii) we get,

19/7=a (22/7)-2

a=11 ans

i hope it will help for you✌
