Answer:
y=2(100-x)
Step-by-step explanation:
Given the expression, knowing also that the expression has two unknowns x and y
2,000 = 20x + 10y
step one:
we can reduce all coefficients by dividing through by a common multiple
i.e dividing through by 10 we have
2,000/10 = 20x/10 + 10y/10
200=2x+y
step two:
we can either solve in terms of x or y
let us solve in terms of y
y=200-2x
step three:
we can factor 2 on the left-hand side we have
y=2(100-x)
