Solve the equation: <br> 8y - 3 = бу + 17

balandron [24]

Hey!

------------------------------------------------

Steps To Solve:

8y - 3 = бу + 17

~Subtract 8y to both sides

8y - 3 - 8y = бу + 17 - 8y

~Simplify

-3 = -2y + 17

~Subtract 17 to both sides

-3 - 17 = -2y + 17 - 17

~Simplify

-20 = -2y

~Divide -2 to both sides

-20/-2 = -2y/-2

~Simplify

10 = y

------------------------------------------------

Hence, the answer is $\Large\boxed{\mathsf{y~=~10}}$

------------------------------------------------

This is a system of equations. You can solve it by substitution or elimination. I'm going to use substitution x - 2y = -4.5; add 2y to each side x - 2y + 2y = -4.5 + 2y; simplify x = 2y - 4.5 2(2y - 4.5) + 3y = 12 4y - 9 + 3y = 12 7y - 9 = 12 7y - 9 + 9 = 12 + 9 7y = 21 y = 3 <--------first answer x - 2y = -4.5 x - 2(3) = -4.5 x - 6 = -4.5 x -6 + 6 = -4.5 + 6 x = 1.5 <--------second answer Check: 2(1.5) + 3(3) = 12? 3 + 9 = 12? 12 = 12; It checks 1.5 - 2(3) = -4.5? 1.5 - 6 = -4.5? -4.5 = -4.5; It checks x = 1.5 and y = 3 <-----------Final Answer
