Ответ:
I think the answer is : 44
a=2 b=4
Step-by-step explanation:
step 1:
substitute each 'a' with a 2, and every 'b' with a 4.
example:
(4 × 2 ) + (2 × 4 ×2) - 2 ( 2 - {3 × 4})
step 2:
solve each number that had a variable (4a, 2b2, 3b)
example:
4a = 4 × 2 = 8
3b = 3 × 4 = 12
2b2= 2 × 4 × 2 = 16
step 3:
solve left to right, but do ( ) first
follow the rules of PEMDAS
• 8 + 16 - 2( 2 - 12)
2 - 12 = -10
• 2 × -10 = - 20
• 8 + 16 = 24
• 24 -(-20) = 44
