Question

What is the missing value of 2x+3y=12

Answer 1

y=0

x=6

Explanation:

2x+3y=12

Make 2x the subject of the formula

Therefore: 2x=12-3y

x=12-3y/2

x=6-3y

So put x=6-3y into the equation

2(6-3y)+3y=12

12-6y+3y=12

12-3y=12

-3y=12-12

-3y=0

y=0/-3

y=0

So put y=0 into x=6-3y

x=6-3y

x=6-3(0)

x=6-0

x=6.
