The steps used to solve this are (for most calculators ) is

log

0.0019

=

If you do not own a scientific calculator, you can use the one that came from windows.

Unfortunately it is slightly different. Make sure you are in scientific mode. Type in 0.0019. Then click on log. Same answer just much longer.

The solution to the system of equation is (3, 6)

Step-by-step explanation:

To solve the  system of the equation given, we will follow the steps below;

y = x + 3   (1)

4x + y = 18 (2)

We can rearrange equation (2) by simply subtracting 4x from both-side of the equation

4x - 4x + y = -4x + 18

y = -4x + 18 (3)

Substitute  equation (1) in equation (3)

x + 3 = -4x + 18

collect like terms

x + 4x = 18 - 3

5x = 15

Divide both-side of the equation by 5

5x/5  = 15/5

x = 3

Substitute  for x = 3 in equation (1)

y = x + 3

y = 3 + 3

y = 6

x= 3  and y = 6

(x,y)

(3, 6)
