The answer is -4.5 (-9/2) and here's why 4x+18=0 4x=-18 divide by 4 x = -18/4 x = -4.5 when you solve the solution you'll see that when you plug in -4.5 in the original solution you see this... (-4.5)(4) = -18 -18+18 = 0
The answer to the math problem of 18 minus 4x equals negative 2 is x equals 5.
Let the number be x: 4x-12 = 60 4x = 60+12 4x = 72 x = 18
Given: 5X - 18 = 4X + 4; subtracting 4X from each side: X - 18 = 4; adding 18 to each side, X = 22
x=18
