Answer:
x = y = (0,26)
Step-by-step explanation:
First find the x intercept
To find the x intercept, substitute 0 for y and solve for x.
Rewrite the equation as
Subtract 6 from 0.
Divide each term in by 4.
Cancel the common factor of 4.
Simplify
Subtract 5 from both sides of the equation.
To write as a fraction with a common denominator, multiply by
·
Combine and
.
Combine the numerators over the common denominator.
Simplify the numerator.
Move the negative in front of the fraction.
x =

Find the y-intercepts.
To find the y-intercept(s), substitute in 0 for x and solve for y.
Add 0 and 5.
Multiply 4 by 5.
Add 6 to both sides of the equation.
Add 20 and 6.
y = (0, 26)
Answer:
Given statement: Ivan and Tanya share £150 in the ratio 4:1
let the number be x.
Then, the share of Ivan be 4x and the share of Tanya be x.
From the given scenario,
the equation that would best represent the given will be;
Combine like terms;
Divide both sides by 5 we get;
Simplify:
x =£30
Then,
the share of Ivan is, 4x =
and the share of Tanya is, x =£30
Therefore, £90 more Ivan gets compared to Tanya.
