Answer:
3x = 24
Step-by-step explanation:
14x - 2x + 3 = 3(5x +9)
12x +3 = 15x + 27
Mai was subtracted 5x instead of multiplying the 3 by the 5x and the 9.
3x = 24
-im pretty sure I did my math right but correct me if I'm wrong
Noah added the 15x to the 12x I think he was supposed to subtract the 12x from the 15x then minus the 3 from the 27 which they both got right.

Answer:
-20
Step-by-step explanation:
Let the number be Y
If the sum of a number and seven is doubled, the result is six less than the number, The statement is as expressed below
2(Y+7)= Y-6
Find the value of Y
2Y+14=Y-6
Put the like terms together
2Y-Y=-6-14
Y=-20
The number is therefore -20
<em>Verifying</em>
2(-20+7)=-20-6
2(-13)=-26
<u>-26=-26</u>
Answer:
(-5,8)
Step-by-step explanation:
The left number represents the x-axis, the right one the y-axis. A translation to the right means in the positive direction on the x-axis, which is why we add 3 to -8 which gives us -5. Down on the y-axis is in the negative direction, which means we have to subtract 1 from 9, giving us 8.
