Question

answer the questions below using the lesson classroom notes. then answe
1.) what is an equation? what does the equal si
lesson 3 practice problem #1 (adapted
2.) solve: $x + 3y = 4x + y$ when $x = 6$
.) what are some acceptable moves that yo maintains the balance/equality of both si

Explanation:

Step1: Substitute x=6 into equation

$6 + 3y = 4(6) + y$

Step2: Simplify right-hand side

$6 + 3y = 24 + y$

Step3: Isolate y terms (subtract y)

$6 + 2y = 24$

Step4: Isolate constant terms (subtract 6)

$2y = 18$

Step5: Solve for y (divide by 2)

$y = \frac{18}{2}$

Answer:

$y = 9$
