Answer:
7
Step-by-step explanation:
1 Simplify -2-4−2−4 to -6−6.
2-19-(-6)\times (-5-(-7))\times 22−19−(−6)×(−5−(−7))×2
2 Remove parentheses.
2-19-(-6)\times (-5+7)\times 22−19−(−6)×(−5+7)×2
3 Simplify -5+7−5+7 to 22.
2-19-(-6)\times 2\times 22−19−(−6)×2×2
4 Simplify (-6)\times 2\times 2(−6)×2×2 to -24−24.
2-19-(-24)2−19−(−24)
5 Remove parentheses.
2-19+242−19+24
6 Simplify 2-192−19 to -17−17.
-17+24−17+24
