Question

I needed an answer AND explanation that if this is true, or false:
" 8+(-7) - (-4) = 8 + 7 - 4 "​

Answer 1

Answer:

Simplifying

8 + (-7) + -1(-4) = 8 + 7 + -4

8 + -7 + -1(-4) = 8 + 7 + -4

Multiply -1 * -4 8 + -7 + 4 = 8 + 7 + -4

Combine like terms: 8 + -7 = 1 1 + 4 = 8 + 7 + -4

Combine like terms: 1 + 4 = 5 5 = 8 + 7 + -4

Combine like terms: 8 + 7 = 15 5 = 15 + -4

Combine like terms: 15 + -4 = 11 5 = 11

Solving 5 = 11

ANS False
