Step-by-step explanation:
Use the distributive formula to solve for x:
a(b + c) = ab + ac
-3(4x - 2) = 21 - 4(1 + 4x)
1. Use distributive property:
-12x + 6 = 21 - 4 - 16x
2. Simplify:
-12x + 6 = 17 - 16x
3. Add 16x to both sides
-12x + 16x + 6 = 17 - 16x + 16x
4. Simplify:
4x + 6 = 17
5. Subtract 6 from both sides
4x + 6 - 6 = 17 - 6
6. Simplify
4x = 11
7. Now, divide both sides by 4
4x/4 = 11/4
8. Simplify:
x = 11/4 <------ Answer
