John and Andrew have £3.40 between them. John has £1.20 more than Andrew. John has £u and Andrew £v

A) write two equations in u and v.

B) solve them to find the values of u and v.

In the given question, there are several information's of immense importance and they can be used to find the necessary answers. It is already given that John and Andrew have 3.40 pound together. It is also given that John has 1.20 pound more than Andrew. It is also assumed that John has"u" pound and Andrew has "v" pounds.

Then we can write the two equations as

u + v = 3.40

u = v + 1.20

To find the values of u and v, we can replace the u in the first equation with the value of u in the second equation. Then

u + v = 3.40

(v + 1.20) + v = 3.40

2v + 1.20 = 3.40

2v = 3.40 - 1.20

2v = 2.2

v = 2.2/2

= 1.1

Now we replace the value of v in the first equation to find the value of u.

u + v = 3.40

u + 1.1 = 3.40

u = 3.40 - 1.1

u = 2.3
