# How do I work this out

8v = 2 i1 + 6 ( i1+ i 2)
5v = 4 i2 + 6 ( i1 + i2 )
Are the vs voltages?
If so, you have two linear equations in 2 unknowns i1 and i2 so just solve as per gcse work

Youve changed the reply, but Im presuming you;ve already set up the equations using Kirchoffs laws and simply needed to solve them. If not, can you upload the original question and how you came up with those equations.

That is the original question.

No text at all? If there is no description of a circuit, its a bit tricky to apply Kirchoffs laws.

I think you must've misunderstood your teacher. You can't solve a pair of simultaneous equations using kirchoff's laws. They probably meant that you should derive those equations using Kirchhoff's laws and then solve them as you would any other simultaneous equations.
