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
