Question

aripotta · Answer

what do you get when you solve for x in the second equation?

anonymous · Answer

idk that all the problem gave me

aripotta · Answer

yea, you have to solve for a variable first before you can substitute anything. so solve for x in terms of y in the second equation

aripotta · Answer

x+y=4
just rearrange the equation so that it's just x on the left side

anonymous · Answer

What you can do is use one of the equations to express x in terms of y, and then substitute that into the other equation.
