Answer:
X= 18; Y=15
Step-by-step explanation:
As a student myself working this out I cannot explain how I got the answer but I know it is correct.
Well, you can estimate the decimal. For example if you have 1.35678 you can round the three to a four because there is a 5 beside it so the estimated decimal would be 1.4, 1.4 as a fraction would be 1 4/10 which can be simplified down to 1 2/5.
£110 as 45mins times 4 radiators divided by 60 mins =3 hours
3 hours + 1 hour = 4 hours
4 hours times £20= £80
£80+£30=£110

X + 4y = 36
Solving
X + 4y = 36
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '-4y' to each side of the equation.
X + 4y + -4y = 36 + -4y
Combine like terms: 4y + -4y = 0
X + 0 = 36 + -4y
X = 36 + -4y
Simplifying
X = 36 + -4y</span>
The answer is 1 since that’s the first place that the line crosses through on the y-axis.
