Answer:
answer is 3.2
Explanation:
Simplifying
8[4 + -1a] = 2a
[4 * 8 + -1a * 8] = 2a
[32 + -8a] = 2a
Solving
32 + -8a = 2a
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-2a' to each side of the equation.
32 + -8a + -2a = 2a + -2a
Combine like terms: -8a + -2a = -10a
32 + -10a = 2a + -2a
Combine like terms: 2a + -2a = 0
32 + -10a = 0
Add '-32' to each side of the equation.
32 + -32 + -10a = 0 + -32
Combine like terms: 32 + -32 = 0
0 + -10a = 0 + -32
-10a = 0 + -32
Combine like terms: 0 + -32 = -32
-10a = -32
Divide each side by '-10'.
a = 3.2
Simplifying
a = 3.2
