How do you solve this equation using substitution:
3x-y=14
2x+y=16

Question

anonymous · Answer

the Y values cancel each other out so it becomes 5x=30, 5 divides into 30 6 times.

anonymous · Answer

using substitution, not elimination

anonymous · Answer

Or solve one of the equations for y, then plug it in to the other equation.

anonymous · Answer

Like y=-2x+16, then plug this into the other one:
3x-(-2x=16)=14
Solve for x, then place this the number back into the first equation.

anonymous · Answer

So 3x+2x-16=14
5x-16=14
x=6

anonymous · Answer

So x=6 and now place that back into the other equation:
2(6)+y=16
12+y=16
y=4
