Jamal uses the steps below to solve the equation 6x – 4 = 8.

step 1: 6x – 4 + 4 = 8 + 4
step 2: 6x + 0 = 12
step 3: 6x = 12
step 4: =
step 5: 1x = 2

step 6: x = 2

which property justifies step 3 of his work?

"if equals are divided by equals, the results are equal." This is a corollary of the distributive property for multiplication.

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
