4x = 7(x-3)
1. Distribute that multiplicand 7: 4x = 7x - 21
2. Group the x terms together: Subtract 4x from both sides: 0 = 3x - 21
3. Solve for x: Add 21 to both sides: 21 = 3x
4. Divide both sides by 3 to obtain x = 7 (answer)
20x + 15y = 2000
x + y = 115
55+60=115
20 (55) + 15 (60)=2000
1100+900=2000
2000=2000
1. 7 : 07
2. 9 : 45
3. 6
4. 2 : 25
5. 8
6. 17
Answer:
Choice 2) 5x+15
Step-by-step explanation:
We can write the equation 9x=4500
Now we just solve for x by dividing both sides by 9 to get:
x=500
