Answer:
x=4
Step-by-step explanation:
Simplifying
-1(7 + -4x) = 9
(7 * -1 + -4x * -1) = 9
(-7 + 4x) = 9
Solving
-7 + 4x = 9
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '7' to each side of the equation.
-7 + 7 + 4x = 9 + 7
Combine like terms: -7 + 7 = 0
0 + 4x = 9 + 7
4x = 9 + 7
Combine like terms: 9 + 7 = 16
4x = 16
Divide each side by '4'.
x = 4
it means to place the little dot (or decimal) in the correct position next the number. Makes sense?
Answer:
Now, derive it from the calculations
Step-by-step explanation:
Net income = 100% = N120,000
therefore
1. Food
40%/100% = 2/5 of N120,000
= N48,000
2.Housing
30%/100% = 3/10 of N120,000
= N36,000
3. Savings
20%/100% = 2/10 (or 1/5) of N120,000
= N24,000
4. Miscellaneous
10%/100% = 1/10 of N120,000
= N 12,000
