Check Format
Equation 1 is in the correct format.
Check Format
Equation 2 is in the correct format.
Set up standards equations
Standard equation 1 = ax + by = c and Standard equation 2 = dx + ey = f.
Find a, b, c in ax + by = c
3y + n = 250
a = 3, b = 1, c = 250
Find d, e, f in dx + ey = f
y + n = 150
d = 1, e = 1, f = 150
Step 1, calculate Delta (Δ):
Δ = a * e - b * d
Δ = (3 * 1) - (1 * 1)
Δ = 3 - 1
Δ = 2
Step 2, calculate the numerator for y
Numerator(y) = c * e - b * f
Numerator(y) = (250 * 1) - (1 * 150)
Numerator(y) = 250 - 150
Numerator(y) = 100
Step 3, calculate the numerator for n
Numerator(n) = a * f - c * d
Numerator(n) = (3 * 150) - (250 * 1)
Numerator(n) = 450 - 250
Numerator(n) = 200
