Answer:
Step-by-step explanation:
4x+3=-9-3(x+9)
Distributing 3 over (x+9)
4x+3=-9-3x-27
Adding 3x in both sides and subtracting 3 from both sides
4x+3+3x-3=-9-3x-27+3x-3
4x+3x=-9-27-3
7x=-39
Dividing both sides by 7 we get

Answer:
Tom: 132 Bob: 396 Keisha: 139
Step-by-step explanation:
132 x 3
132 + 7
Answer:
x = -2
Step-by-step explanation:
You would first distribute.
<u>6(3x + 7)</u> = <u>-5(4x - 3)</u> - 49 → 18x + 42 = -20x + 15 - 49
We can then calculate difference of 15 and 49.
18x + 42 = -20x <u>+ 15 - 49</u> → 18x + 42 = -20x -34
We can now move the variables to one side of the equation and the numbers on the other side.
18x + 20x + 42 - 42 = -20x + 20x - 34 - 42 → 38x = -76
Then, divide.
38x ÷ 38 = -76 ÷ 38 → x = -2
