Help Please, solving equations. Photo attached.
ive got only a few mins left.
can you solve the 1st equation for "y"?
no can you just explain please.
@jdoe0001
Y=16-4x now sub that in for y in first equation
can you help me? i dont really know how to do this.
ohh, sorry I was ... a bit away for a bit yes, you solve for "a variable" in one equation, and substitute on the 2nd :) if you were to solve the 1st one for say "y", what would it look like?
i dont know....
can u show me how to just solve it...
well, you can check on how to simplify equations at http://www.youtube.com/watch?v=IIDTlgvo0DM
y = 16-4x Substituting this into 2nd equation: 2x + 3(16-4x) = -2
ok [:
2x +48 -12x = -2 2x -12x = -50 -10x = -50 x = 5 Now can you solve for y?
yes i need to move on to another question my time is runnning out THANKS!
u r welcome
