Notice that y has the same coefficient (ignoring the sign) in both equations. So, we will use the elimination method. The elimination method means that we will combine the two equations to eliminate the y...

First recognise that (x+5w/2)^0.5 is the same as the square root of (x+5w/2). Then square both sides of the equation to get: y^2=(x+5w/2).Multiply both sides by 2 to eliminate the fraction from the RHS: 2...

1. write out each equation one underneath the other so that the x’s are in one column and the y’s are in another.2) we also need to make sure that the numbers are also aligned up3) for 4x - 17 = 5y, we...

When it comes to accents, it helps to say the word aloud to realise where the word's emphasis is and therefore where the accent is. For example, take the word 'decisión'. This word's emphasis is on the la...

Current is defined as the flow of electrons. This flow is caused by the electrons within the wire being pulled by electric field. As the electrons travel through the wire they collide with the atoms that...
