Answer:
The solution set is (4, 3)
Step-by-step explanation:
To solve by substitution, start by solving the second equation for y.
2x - y = 5
-y = -2x + 5
y = 2x - 5
Now that we have this, put that expression in for y in the first equation and solve for x.
5x - 2(2x - 5) = 14
5x - 4x + 10 = 14
x + 10 = 14
x = 4
Now that we have the value of x, input it into either equation and solve for y.
2x - y = 5
2(4) - y = 5
8 - y = 5
-y = -3
y = 3

The digit in the units place is 1/10 of the digit in the hundreds place (80÷10=8)
The digit in the hundreths place is 1/10 of the digit in the tenths place (0.9÷10=0.09)
The digit in the tenths place is 10 times as much as the digit in the hundreths place (0.09×10=0.9)
