Ответ:
-4(x + 4x) = 2(2 - x)
Step-by-step explanation:
1. Use the distributive property to solve: a(b + c) = ab + ac
-4x - 16x = 4 - 2x
2. Simplify:
-20x = 4 - 2x
3. Add 2x to both sides:
-20x + 2x = 4 - 2x + 2x
4. Simplify:
-18x = 4
5. Then, divide both sides by -18:
-18x/-18 = 4/-18
6. Simplify:
x = -2/9 < Correct
But your multiple choices are incorrect, so maybe you didn't write down the question right because my answer is correct- given the steps showing how to do it.
But, Hope this helped!!!
