if you want to work out what x is this how you do it:
3(3+x)=99
9+x=99 (expand the brackets)
x=90 (-9)
remember what you do on one side you have to do it one the other
divide 9 by 17, gives 0.5294
Multiply by 10...
n - 7 = -1 Add 7 to each side: n = -1 + 7 n = 6
1/3 + x = 1/2 x = 1/2-1/3 = 1/6
8x+4 = 2x+28 8x-2x = 28-4 6x = 24 x = 4
294
its a sovle from a story ex: the boy left and fell his mom help him
some accepted them as migrants.
divide 9 by 17, gives 0.5294
Without an equality sign the expression given can't be considered to be an equation
Multiply by 10...

Comment answer)) What Kind of problem? There is a bunch of hard problems, but I need more info on which kind.
-9x = 13.5 Divide both sides by -9 to find the value of x: x = -1.5
-0.2x2+12x+11 = 0 Using the quadratic equation formula will give you two solutions which are: x = 30 + the square root of 955 = 60.90307428 to 8 decimal places. or: x = 30 - the square root of 955 = -0.90307428 to 8 decimal places.
i want a steel structure designed for a reinforced cement concrate dome. please assist me and sovle probalam thanks
You have 2x - 12 = 3 ie 2x = 15 so x = 7.5
