Step 1 add 4x to both side eliminating it from the left side. 7y-4x=28
+4x=+4x
Step 2 doing that the 4x on the left side will go away and the problem should look like
7y=4x+28
Step 3 you need to isolate the y variable by dividing 7 on both sides. 7y/7=4x/7+28/7
The answer should be y=4/7x+4
+4x=+4x
Step 2 doing that the 4x on the left side will go away and the problem should look like
7y=4x+28
Step 3 you need to isolate the y variable by dividing 7 on both sides. 7y/7=4x/7+28/7
The answer should be y=4/7x+4
x = -7
y = 4
