Find the solution of the system of equations.
– 2 – 8y = -30
2x + 8y = 36

x= 1.5

y= 4.125

Step-by-step explanation:

Step one:

given the two equations

Step two:

let us subtract the equations

divide both sides by 16

put y= 4.125 in equation 2

2^y = ln 5, or   y(ln 2) = ln 5.   solving for y,   y = (ln 5) / (ln 2).   y=5

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
