Question 23250: 5x-2y=11 y=2x-5
Answer by rapaljer(4671)   (Show Source):
You can put this solution on YOUR website! Because one of these equations is in the form of "x=___" or "y=___", the substitution method works well. That is, substitute the y from the second equation into the first equation.
5x-2y=11
y=2x-5
5x-2(______) = 11
5x -2(2x-5)=11
5x - 4x +10 = 11
x=1
Now, substitute the x value into the "y=___ " formula:
y= 2x -5
y=2(1) - 5
y= 3
Last, check by substituting BOTH values into the OTHER equation:
5x-2y=11
5(1)-2(-3) = 11
5+6 =11
It checks!!
