4) y = 5x + 10.
4x - 6y = 18

Step-by-step explanation:

this is easy let me explain

y= 5x + 10

step 1: flip the equations

(so it can look like this)

5x + 10 = y

step 2: add -10 to both sides

5x + 10 + -10 = y + -10

5x = y - 10

step 3: divide both sides by 5

5x y - 10

=

5 5

and your answer is

1

x = --- y - 2

5

4x - 6y = 18

step 1: add +6y to both sides like this

4x - 6y = 18

+ 6y + 6y

(-6y and + 6y cancel each other out) so it will be like this

4x = 6y + 18

step 2: divide both sides by 4

4x 6y + 18

=

4 4

3 9

x = --- y +

2 2

there you go

and if you want, you can add them but that's the )
