x4y=14 2x=y+1
Let's look at your two equations.
x  4y = 14
2x = y + 1
Let's solve the second equation for y:
y = 2x  1
Now let's substitute (2x  1) for y in the first equation:
x  4(2x  1) = 14
x  8x + 4 = 14
9x + 4 = 14
9x = 18
x = 2
Substitute 2 for x in the second equation and solve for y:
2(2) = y + 1
4 = y + 1
y = 3
Check these values with the original equations. It always helps to check your work!
I hope this will help.
