Question

What is the value of x in the equation 2x +3y = 36, when y=6?
O9
O 27
O 36

Answer 1

your answer is 9.
explanation: when plugging in 6 to 3y you get 18. 3(6)=18. from there you have 2x+18=36. subtract 18 on both sides. 36-18. you get 18. then divide 18 by 2 and you get 9.

Answer 2

x=9

Explanation:

Substitution and solving

`2x+3y=36\\2x+3(6)=36\\2x+18=36\\2x+18-18=36-18\\36/2=2x/2\\x=9`
