Solve for x.
x - 1/2 (8 - x) = x + 3(4 - x) - x

x = 32/9

Step-by-step explanation:

Performing the indicated multiplication from left to right yields:

x - 4 + x/2 = x + 12 - 3x - x

Combining like terms on both sides, we get:

(3/2)x - 4 = -3x + 12

Adding 4 to both sides simplifies this equation to:

(3/2)x = -3x + 16, or

(3/2)x + (6/2)x = 16, which simplifies to:

3x + 6x = 32, or 9x = 32.

Then x = 32/9

c

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
