Given: 8x3-12x
Step 1: Divide by x
8x2-12
Step 2: Divide by 4
2x2-3
Step 3: Set it equal to zero
2x2-3=0
Step 4: Add 3 to both sides
2x2=3
Step 5: Divide both sides by 2
x2=3/2
Step 6: Simplify
x2=1.5
Step 7: Square root both sides
x=approx. 1.225
Did this help?
If: 8x+12x = 90 Then: 20x = 90 And: x = 4.5
4x+8x+3 = 12x+3
10x - 5y + 2x - 3y = 12x - 8y
8x = 120divide the equation by 8 8x/8 = 120/8 x = 15
-12x = 72 Divde both sides by -12 to find the value of x: x = -6
8x-1=23-4x 12x=24 x=2
The GCF is 4x.
OK, SO 4x = 12x + 32.SO 4x -12x-12x-12x+32 (subtract 12x from each side to get x on one side)SO -8x = 32 (simplify)SO -1 (-8x) = 32 (-1) (multiply each side by -1)SO 8x -32 (simplify)SO 8x / 8 = -32/8 (divide each side by eight (8) to get ""X"" by itself)SO x= -4SO x = -4.Does that help?Hope that helps!
8x-3+6x-1 = 12x+614x-4 = 12x+614x-12x = 6+42x = 10x = 5
-4
If: 8x+12x = 90 Then: 20x = 90 And: x = 4.5
If the equasion is 12x+6-8x-4x-3+12 then the answer is 15.
Do you mean 8x2+12x+28?? If so, plug 8,12, and 28 into a,b, and c of this website http://www.math-booster.com/calculators/quadratic-formula.html the answer is imaginary or No Solution
4x+8x+3 = 12x+3
Subtract 7 from each side: 12x = 8x + 16Subtract 8x from each side: 4x = 16Divide each side by 4: x = 4
10x - 5y + 2x - 3y = 12x - 8y
If you're trying to find x: 8x-1=-4x+23 8x+4x=23+1 12x=24 x=24/12 x=2 wasn't really sure if that's what your question was but hope it helped =)
