Dx+t=10
-t -t
dx=10-t
÷d ÷d
x=(10-t)/d

Answer:
Probably because learning to do polynomials by hand boosts understanding of the topic and improves general algebraic solving ability,both of which are required in further topics like advanced calculus and algebra
Answer: 23
Step-by-step explanation:
Benches = x
4x + 3 = 5x - 2
x = 5
this equals that x = 5 because we put the unknown algebraic number on one side and the numerals on the other.
So if there are 5 benches then the number of children will be
4 * 5 + 3 or 5 * 5 - 2, which both equal 23.
Therefore, the answer to this question is 23 children
