(7z-1)/2=3z-2
Least commom multiple=2
7z-1=2*(3z-2)
7z-1=6z-4
7z-6z=-4+1
z=-3
Solution=z=-3
So r+c=42
c=4+r
subsitute c=4+r for r in r+c=42
r+4+r=42
add like terms
2r+4=42
subtract 4 from both sides
2r=38
divide both sides by 2
r=19
rob=19
subsitute r=19 for r in c=4+r
c=19+4
carly=23
Answer:
2( 2x - y ) -4( x - y ) +3y
4x - 2y - 4x + 4y + 3y
-2y + 4y + 3y
-2y +7y
5y
