6*100 = 600
600 + 38 = 638
therefore the answer is:
638/100
however this is an improper decimal.
Any value as long as P = Q
For the equation to have infinitely many solutions, we require both sides of the equation to have exactly the same terms.
3x + 4y = 16
-4x - 3y = -19
4( 3x + 4y = 16)
3( -4x - 3y = -19)
Distribute
12x + 16y = 64
-12x - 9y = -57
Now subtract both equations
7y = 7
/7 on both sides
y = 1
Substitute y = 1 in one of the equations.
3x + 4y = 16
3x + 4(1) = 16
-4 on both sides
3x = 12
/3 on both sides
x = 4
Answer:
x = 4
y = 1
