Answer:
6x + 3
General Formulas and Concepts:
<u>Pre-Algebra</u>
Distributive Property
Order of Operations: BPEMDAS
Step-by-step explanation:
<u>Step 1: Define</u>
3(2x + 1)
<u>Step 2: Expand</u>
the first one if you solve it it will be the same and the second one 41/7
y = 4x + 6
-5x - 4x - 6 = 21
-9x - 6 = 21
-9x = 27
x = -3
y - 4(-3) = 6
y + 12 = 6
y = -6
(-3, -6)
