Answer:
x=4
Step-by-step explanation:
(-x+3)-(x-5)=2x+8
(-x+3)+(-x+5)=2x+8
-x+3-x+5=2x-8
-2x+8=2x-8
-2x-2x=-8-8
-4x=-16
x=-16/-4
x=4
Step-by-step explanation:
Given:
To find:
Solution:
(multiplication of digits give a larger number compared to addition, subtraction and division)
= (12 × 7) × (4 + 1)
∴ The biggest number Tony can make is 420.

Answer:
x = - 5
Step-by-step explanation:
Given
f(x) =
The denominator of f(x) cannot be zero as this would make f(x) undefined. Equating the denominator to zero and solving gives the value that x cannot be.
solve : 3x + 15 = 0 ⇒ 3x = - 15 ⇒ x = - 5 ← excluded value
Domain x ∈ R , x ≠ - 5
