x would be 6 because you double 5 to get ten, so you double 3 to get 6
Answer:
x = y - a
Step-by-step explanation:
y = x + a ( subtract a from both sides )
y - a = x
Answer:
2x + 3
Step-by-step explanation:
(10x² + 19x + 6) ÷ (5x + 2) =
= (10x² + 15x + 4x + 6) ÷ (5x + 2)
= [5x(2x + 3) + 2(2x + 3)] ÷ (5x + 2)
= [(5x + 2)(2x + 3)] ÷ (5x + 2)
= 2x + 3
