Solve using the substitution method.​

Mathematics
1 answer:
maxonik [38]4 years ago
8 0

Answer:

The solution is d = 3 and e = -1

Step-by-step explanation:

To solve using the substitution method, we need to first solve the second equation for d.

d - e = 4

d = e + 4

Now that we have the value of d, we can put it in for d in the first equation and solve for e.

d + e = 2

(e + 4) + e = 2

2e + 4 = 2

2e = -2

e = -1

Now that we have this value, we can plug it into the original equation and find d.

d + e = 2

d + -1 = 2

d = 3

Quantitative data is information that can be measured, while qualitative data is descriptive data which can not be measured.
All five measures (the mean, the median, the trimmed mean, the weighted mean and the mode) can be calculated for quantitative data only, because they all use values in order to be calculated.
