5,432+x-5-4-32-x=5,391
(32 + (4 x 4 x 4)) / 8 = 12
x2 + 4x - 32 = (x + 8)*(x - 4)
To solve x + x + x + x, set the problem up as multiplication like this 4x = 128. Divide both sides of the problem by 4. You will get x = 32. To check your work, substitute 32 for the x and do the math. 4 x 32 = ?. If the answer is 128, the answer is correct.

5,432+x-5-4-32-x=5,391
(32 + (4 x 4 x 4)) / 8 = 12
(x + 4)(x + 8)
x2 + 12x + 32 = (x + 8)(x + 4)
32/4 + 4 x 8 = 8 + 32 = 40
x² + 8x - 48 = (x + 12)(x - 4) x² + 8x + 48 = (4+(√32)i)(4-(√32)i)
x2 + 4x - 32 = (x + 8)*(x - 4)
x2 + 12x + 32 = (x + 4)(x + 8)
To solve x + x + x + x, set the problem up as multiplication like this 4x = 128. Divide both sides of the problem by 4. You will get x = 32. To check your work, substitute 32 for the x and do the math. 4 x 32 = ?. If the answer is 128, the answer is correct.
