set them equal to eachother, you will end up with x8 = 8x 71, solve for x

so I have 8x71=1x=8
explain to me what I do from here?
I subtract 71 from both sides here?

i would start by subtracting \(x\) from both sides, to put all the terms with \(x\) on the left

in other words get \(7x71=8\)

solution of a set of equation means
dw:1364000497143:dw
find the point P(x,y)
which satisfies all the equations.

then add 71 to both sides to get
\[7x=63\] and finally divide both sides by \&\)

that, is , finally divide both sides by \(7\)

so how would I find y now since I know x?

you replace \(x\) by \(9\) in either equation

set them side by side like this:
x8=8x71
subtract 8 on both sides and add 8 to both sides
now you should get 7x=63

now plug byour answer back into the first equation to get y
