° 4 × (10 - 2 × x) - (4096)
° 10-2x = -2 (x-5)
° -8 × (x-5)-4,096 which equals 0
° -8x - 4,056 = -8 × (x + 507)
° -8×(x + 507) which also equals 0
° -8 = 0 (solve this⬅)
° x + 507 which equals 0
°Sub. "507" from each side(s)
So, that means your answer would have to be "x" = ➡'-507..'
Hopes this explanation helps
