(6x–1)(6x+1) - 4x(9x+2) = −1
Simplify the left side:
36x^2-1 -36x^2-8x = -1
Combine like terms:
-1 -8x = -1
Add 1 to both sides:
-8x = 0
Divide both sides by -8:
x = 0 / -8
x = 0
The root is 0
The value of x is 15
1/3 distributed to (3+2x) = (1+2/3x)-1
1-1 will leave u with 2/3x=10
solve for x and u get 15
w = 13
x = 9
y = 1.9
z = 0.5
w + x + y Plug in the numbers for each variable
13 + 9 + 1.9
22 + 1.9
23.9 The third option is your answer
