Answer:
x=1
Step-by-step explanation:
3x-y=3
y=3-3x
9x-3y=9
9x-3(3-3x)=9
9x - 9 + 9x=9
9x + 9x=9 + 9
18x=18
x=18÷18
x=1
Answer:
16 x¹⁰ + 88 x⁵ + 121
step-by-step explanation:-
( 4 x⁵ + 11)²
- use ( a + b)² = a² + 2ab + b² to expand the expression
( 4x ⁵)² +2 ( 4x⁵) ( 11 ) + ( 11 )²
calculate we get
16 x¹⁰ + 88 x⁵ + 121
