Question 16293: Can you please help me solve {4x+2y=7
{y=5x
Answer by pwac(253) (Show Source): You can put this solution on YOUR website!
Use same principle as before
4x+2y=7 ----(1)
y=5x ----(2)
Sustitute value of y in (1) with value of y in(2)
4x+2(5x)=7
4x+10x=7
14x=7
Substitute this into (2) to find y
y=2.5
so x=0.5 and y=2.5 check by putting values into original equations
