Solve for "y" > 15y + 14 = 2(5y + 6)
First: eliminate the parenthesis > multiply the outer term with the terms in parenthesis....
15y + 14 = 2(5y) + 2(6)
15y + 14 = 10y + 12
Sec: combine "like" terms...subtract "14" from both sides...
15y + 14 - 14 = 10y + 12 - 14
15y = 10y - 2
*Subtract "10y" from both sides...
15y - 10y = 10y - 10y - 2
5y = - 2
Third: isolate "y" on one side > divide both terms by "5"...
5y/5 = - 2/5
y = -2/5

Use distributive property:
15y+14=10y+12
Subtract 10y from both sides:
5y+14=12
Subtract 14 from both sides:
5y=-2
Divide 5 from both sides:
y=-2/5
Check:
15(-2/5)+14=2(5(-2/5)+6)
-2(3)+14=2(-2+6)
-6+14=2(4)
8=8
I hope this helps!

15y+14=2(5y+6)
15y+14=10y+12 (distributive property)
5y+14=12 (subtract 10y for both sides)
5y= -2 (subtract 14 for both sides)
y= -2/5 (divided 5 for both sides)

15y + 14 = 10y +12
(15y-10y) = 12 - 14
5y = -2
y = -2/5
