Sagot :

I can only do number 1 sorry :(
4x+y=2x-y what you have to do is sort the numbers into x and y so it becomes 4x - 2x = -y -y. (Remember when it crosses the = it becomes minus!) Then solve it to get 2x = -2y = 3      so x is 0.66 and y is -0.66 I guess?
I am probably wrong because I am not good at algebra but good at other stuff
