Question

a÷b=(3/2)^2×(2/3)-4 find the value of (a÷b)-3​

Answer 1

Answer:

The given equations are

2

a

+3

b

=17 .....(i)

2

a+2

−3

b+1

=5 ...(ii)

⟹2

a

×2

2

−3

b

×3=5

⟹4×2

a

−3×3

b

=5

We put 2

a

=x & 3

b

=y.

Then the equations become

x+y=17 ...........(iii) &

4x−3y=5 ........(iv).

(iii)×4⟶4x+4y=68.....(v).

(iv)−(v)⟶7y=63

⟹y=9=3

2

.

∴3

b

=3

2

⟹b=2.

Again putting y=9 in
