Ответ:
The value should be -62!!
Ответ:
- 62
Step-by-step explanation:
Calculate the sums within the brackets first and then multiplication, as stated by the BOMDAS rule.
B = Brackets
O = ?
M = Multiplication
D = Division
A = Addition
S = Substitution
(- 6 + 4) = -2
(5 + 9) = 14
- 2 × 14 = -28
- 28 - 3 = - 31
2 × - 31 = - 62
Disclaimer: I am not sure if one of the x's is used as a variable or not
Ответ:
7x=28-14
7x=14 divide by 7
x=2
6x+50=110
6x=110-50
6x=60 divide by 6
x=10
