Use Cramers method to solve:
o + t = 700
2o + 1.25t = 1250
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
o + t = 700
a = 1, b = 1, c = 700
Find d, e, f in dx + ey = f
2o + 1.25t = 1250
d = 2, e = 1.25, f = 1250
Step 1, calculate Delta (Δ):
Δ = a * e - b * d
Δ = (1 * 1.25) - (1 * 2)
Δ = 1.25 - 2
Δ = -0.75
Step 2, calculate the numerator for o
Numerator(o) = c * e - b * f
Numerator(o) = (700 * 1.25) - (1 * 1250)
Numerator(o) = 875 - 1250
Numerator(o) = -375
Step 3, calculate the numerator for t
Numerator(t) = a * f - c * d
Numerator(t) = (1 * 1250) - (700 * 2)
Numerator(t) = 1250 - 1400
Numerator(t) = -150
