Question

Solve the system of equations by substitution
2x+3y=9
y=x−2

Answer 1

Answer: x = 3, y = 1 OR (3, 1)

Explanation:

let 2x + 3y = 9 be [a] & y = x − 2 be [b]

First, lets substitute [b] into [a] and solve for x

2x + 3( x - 2) = 9

2x + 3x = 9 + 6

5x = 15

x = 3

Now, since x = 3, we can substitute for x in [b]

⇒ y = 3 - 2

y = 1

∴ the solution for the system of equations is x = 3, y = 1 OR (3, 1)

Answer 2

so I think u you divide something and you times and then you multiply it
