The "answer" is the number that 'x' has to be in order to
make the statement true. It's usually called the "solution".
10x + 4 = 4x + 9
Subtract 4x from each side of the equation:
6x + 4 = 9
Subtract 4 from each side:
6x = 5
Divide each side by 6:
x = 5/6
10x + 13 = 1710x = 17-1310x = 4x = 4/10x = 0.4
4x-y=2, thereforey=4x-2sub y into 3x+2y=6...3x+8x-4=611x=10x=10/11
6x+58=10x+14 first move the 58 to the other side by subtracting it. 6x=10x-48 Then you move the 10x to the other side by subtracting it. -4x=-48 Then you divide both sides by -4 x=12 is you answer.
5x + 4 = 10x - 5 10x - 5x = 4 + 5 5x = 9 x = 1.8
x-intercept of y equals -4x plus 4 y = -4x + 4 0 = -4x + 4 -4 = -4x 1 = x So 1 is the x-intercept
10x^3 plus 14x^2-4x+16
-31 - 10x = 41 - 4x-31 + 31 - 10x = 41 + 31 - 4x- 10x = 72 - 4x-10x + 4x = 72 - 4x + 4x-6x = 72-6x ÷ -6 = 72 ÷ -6x = -12Check Your Solution:x = -12-31 - 10x = 41 - 4x-31 - 10(-12) = 41 - 4(-12)-31 + 120 = 41 + 48120 - 31 = 41 + 4889 = 41 + 4889 = 89
y=-10x-4
Only if 4 dollars plus 4 dollars equals 8 dollars.And if you had another 4x, you'd have a dozen-x.
The value of x is 11/2
You need to organise your question properly. 3x+2y=4 4x + 3y= 7? Is 4 4x = 44x or 4-4x or 4+4x How can there be 2 equal signs in 1 equation?
8x + 12 = 4x - 4 8x - 4x = -4 - 12 4x = -16 x = -4
