    how do you solve this i've tried many ways and i always get stuck. -4(2x - 3 ) = -8x + 5 you use -4x times 2x first, then you times -3. so you have (-8+12)=8x+5. you know -8+12 is 4, so the equation becomes 4=8x+5. so x is probably a negative number. so

    -x-4y=-14 2x=y+1 Let's look at your two equations. -x - 4y = -14 2x = y + 1 Let's solve the second equation for y: y = 2x - 1 Now let's substitute (2x - 1) for y in the first equation: -x - 4(2x - 1) = -14 -x - 8x + 4 = -14 -9x + 4 = -14 -9x = -18 x = 2
