System of equations algebraically substitution y=x+3 y=2x+5

(-2, 1)

Step-by-step explanation:

y = x + 3

y = 2x + 5

Using substitution, replace "y" in the second equation with what y equals in the first equation:

x + 3 = 2x + 5

     3 =  x  + 5

    -2 = x

Now substitute "x" with -2 and solve for y

y = (-2) + 3

y = 1

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
