Answer:
Explanation:
Work backward:
1. 2x + 23 = 30
Start:
Multiply the equation by 2:
Subtract 30 from both sides
- 2x - 30 = 7 - 30
- 2x - 30 = -23
Add 23 and 30 to both sides:
2. 3x + 19.5 = 30
Start:
Add 6.5 to both sides:
Multiply by 3:
Distributive property:
3. (10x - 20)/ 5 = 3
Start:
Multiply by 10:
Subtract 20:
Divide by 5:
It goes zero positive negative. that is from left to right
Answer:
X = 2
Step-by-step explanation:
Answer:
x = -1
Step-by-step explanation:
Step 1: Write equation
-4(-5x + 2) - 3x - 5 = -30
Step 2: Solve for <em>x</em>
<u>Distribute -4:</u> 20x - 8 - 3x - 5 = -30
<u>Combine like terms:</u> 17x - 13 = -30
<u>Add 13 on both sides:</u> 17x = -17
<u>Divide both sides by 17:</u> x = -1
Answer: 192.75
Step-by-step explanation:
I am answering your question assuming that the three amounts were checks that were written out during the week.
Beginning balance = 345.28
Subtract the total amount of the checks (65.08 + 24.50 + 118.95 = 208.53)
345.28 - 208.53 = 136.75
Next, add the amount of the deposit. 136.75 + 56.00 = 192.75
