Question

-2(3y - 6) + 4(5y - 8) = 92

Answer 1

Explanation:

-6y + 12 + 20y - 32 = 92

14y -20 = 92

14y = 112

y = 8

Answer 2

y = 8

Explanation:

`-2(3y - 6) + 4(5y - 8) = 92\\\\\mathrm{Expand\:}-2\left(3y-6\right)+4\left(5y-8\right):\quad 14y-20\\14y-20=92\\\\\mathrm{Add\:}20\mathrm{\:to\:both\:sides}\\14y-20+20=92+20\\\\Simplify\\14y=112\\\\\mathrm{Divide\:both\:sides\:by\:}14\\(14y)/(14)=(112)/(14)\\\\Simplify\\y= 8`
