Answer 1

a) 6w - 6 = 4w + 20

$6w-6+6=4w+20+6\\\\6w=4w+26\\\\6w-4w=4w+26-4w\\\\2w=26\\\\w=13$

b) x + 5 = 6x + 30

$x+5-5=6x+30-5\\\\x=6x+25\\\\x-6x=6x+25-6x\\\\x-6x=6x+25-6x\\\\x=-5$

c) 9y - 6 = 5y + 30

$9y-6+6=5y+30+6\\\\9y=5y+36\\\\9y-5y=5y+36-5y\\\\4y=36\\\\y=9$

d) 6a - 6 = 30

$6a-6+6=30+6\\\\6a=36\\\\\frac{6a}{6}=\frac{36}{6}\\\\a=6$
