Step-by-step explanation:
Step 1: Define
-12(x + 4) + 14x = 60
Step 2: Solve for x
- Distribute -12: -12x - 48 + 14x = 60
- Combine like terms: 2x - 48 = 60
- Add 48 to both sides: 2x = 108
- Divide 2 on both sides: x = 54
Answer:
x = 54
Step-by-step explanation:
-12(x + 4) + 14x = 60
i) distribute -12 to the whole parentheses of (x+4)
(-12 × x) + (-12 × 4) + 14x = 60
-12x - 48 + 14x = 60
ii) collect like terms
-12x + 14x - 48 = 60
2x - 48 = 60
iii) move constant to the right-hand side and change its sign
2x = 60 + 48
iv) add the numbers
2x = 108
v) divide both sides of the equation by 2
[tex] \frac{2x}{2} = \frac{108}{2} [/tex]
x = 54
