the Y values cancel each other out so it becomes 5x=30, 5 divides into 30 6 times.
OpenStudy (anonymous):
using substitution, not elimination
OpenStudy (anonymous):
Or solve one of the equations for y, then plug it in to the other equation.
OpenStudy (anonymous):
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.
OpenStudy (anonymous):
So 3x+2x-16=14 5x-16=14 x=6

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