<PRE><B>Question 529629</B>
multiplying by 2 to clear the fraction from the 2nd eqn ___ y + 10 = 4x (all the terns are multiplied)


subtracting 10 to find y ___ y = 4x - 10


you now have an equivalent value for y that you can SUBSTITUTE into the 1st eqn


x - 4 = 4x - 10 ___ subtracting x and adding 10 ___ 6 = 3x


solve for x and substitute the value into any of the eqns to find y</PRE>
