Alberto uses the steps below to solve the equation One-half x minus 3 equals 7. Step 1: One-half x minus 3 plus 3 equals 7 plus 3 Step 2: One-half x plus 0 equals 10 Step 3: One-half x equals 0 Step 4: 2 (one-half) x equals 2 (10) Step 5: 1 x equals 20 Step 6: x equals 20

Step-by-step explanation:

Alberto uses the steps below to solve the equation One-half x minus 3 equals 7. Step 1: One-half x minus 3 plus 3 equals 7 plus 3 Step 2: One-half x plus 0 equals 10 Step 3: One-half x equals 0 Step 4: 2 (one-half) x equals 2 (10) Step 5: 1 x equals 20 Step 6: x equals 20.

Which justifies Step 6 of his work? the addition property of equality the identity property of addition the multiplication property of equality the identity property of multiplication.

1/2x - 3 = 7

One-half x minus 3 equals 7.

Step 1: add 3 to both sides

1/2x - 3 + 3 = 7 + 3

One-half x minus 3 plus 3 equals 7 plus 3

Step 2:

1/2x + 0 = 10

One-half x plus 0 equals 10

Step 3: One-half x equals 10

1/2x = 10

Step 4: Multiply both sides by 2

1/2x * 2 = 10 * 2

2 (one-half) x equals 2 (10)

Step 5:

1x = 20

1 x equals 20

Step 6:

x = 20

x equals 20.

identity property of multiplication states that when 1 is multiplied to an equation, the result remains the same.

identity property of multiplication justifies Step 6 of his work

javeir earned 56 dollors more than kyle so kyle and javier had 14w but javier made 56 dollors more so 14w plus 56 equals 70w so kyle has 14w
