Subtract 1 from both sides

3x = 511 - 1

Simplify 511 - 1 to 510

3x = 510

Divide both sides by 3

x = 510/3

Simplify 510/3 to 170

What is Y-3x=-2 and Y+x=-6

love history [14]

Rearranging the first equation gives:

$y=3x-2$

Substituting this into the other equation gives:

$y+x=-6
\\(3x-2)+x=-6
\\4x-2=-6
\\4x=-4 \\x=-1$

If x=-1:

$y+(-1)=-6
\\y=-5$

So x=-1, y=-5
