Answer:
Distributive
Step-by-step explanation:
1. Distributive Property a • (b + c) = a • b + a • c
2. Commutative Property of Addition a + b = b + a
3. Commutative Property of Multiplication a • b = b • a
4. Associative Property of Addition a + (b + c) = (a + b) + c
Alan will be 50 yrs old and Aron will be 20 yrs old
Step 1 :
g
Simplify —
f
g
f - (((f • —) + g) - d) = 0
f
Step 2 :
f - 2g + d = 0
Step 3 :
3.1 Solve f-2g+d = 0
356 - 50 = 306
306 / 17 = 18

72 + x = 2(81)
multiply 2(81)
72 + x = 162
subtract 72 from both sides
x = 90
