Question

Help please!!!!!!!!!!

Answer 1

`3x+15y=45`

`x+5y=15` ↦ Divide the whole equation by 3.

`5y=15-x` ↦ Move the x to another side.

`y=(15-x)/(5)` ↦ Move 5 to divide 15-x

`y=(15)/(5)-(x)/(5)` ↦ Separate

`y=3-(x)/(5)` ↦ Divide 15 by 5 as we get 3.

`y=-(x)/(5)+3` ↦ Arrange in the form of y = mx + b or the slope-intercept form.

That's the answer.
