Question

what is the value of a. 28-4a=6+2a-2)+24​

Answer 1

Answer:

Simplifying

28 + -4a = 6(2a + -2) + 24

Reorder the terms:

28 + -4a = 6(-2 + 2a) + 24

28 + -4a = (-2 * 6 + 2a * 6) + 24

28 + -4a = (-12 + 12a) + 24

Reorder the terms:

28 + -4a = -12 + 24 + 12a

Combine like terms: -12 + 24 = 12

28 + -4a = 12 + 12a

Solving

28 + -4a = 12 + 12a

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-12a' to each side of the equation.

28 + -4a + -12a = 12 + 12a + -12a

Combine like terms: -4a + -12a = -16a

28 + -16a = 12 + 12a + -12a

Combine like terms: 12a + -12a = 0

28 + -16a = 12 + 0

28 + -16a = 12

Add '-28' to each side of the equation.

28 + -28 + -16a = 12 + -28

Combine like terms: 28 + -28 = 0

0 + -16a = 12 + -28

-16a = 12 + -28

Combine like terms: 12 + -28 = -16

-16a = -16

Divide each side by '-16'.

a = 1

Simplifying

a = 1

Answer 2

28-4a=6(2a-2)+24

4 -4a = 12(a-1)

take 4 common both sides

1+ a = 3(a-1)

a+1=3a-3

2a=4

a= 2
