Well first you want to be trying to solve for the same variable in both problems. Lets solve for Y.
This means we must make both equations say " Y="

first we subtract 12x from both sides of "12x-3y=3" which leaves us with
-3y=3-12x and y=4x-1.

you are basically going to merge the 2 problems by adding "1" to both problems and then subtracting "4x" from both as well as subtracting "y" from both. This gets rid of a variable in one problem and essentially puts in to the other in the process.

This leaves you with -4y=4-16x
Can you solve from there?

Answer:

x = $\frac{42}{5}$

Step-by-step explanation:

Given

19 - $\frac{5x+6}{4}$ = 7 ( subtract 19 from both sides )

- $\frac{5x+6}{4}$ = - 12

Multiply both sides by - 4 to clear the fraction and the negative signs

5x + 6 = 48 ( subtract 6 from both sides )

5x = 42 ( divide both sides by 5 )

x = $\frac{42}{5}$
