You have to distribute!
6(x) = 6x and 6(-6)=-36
So now you have 6x-36=-3(-x+3)
Now do the same on the other side.
-3(-x)=3x -3(3)=-9
So now, 6x-36=3x-9
Combine the like terms:
Subtract 3x in both sides.
6x-3x=3x
Now: 3x-36=-9
Add 36 in both sides.
3x=27
Divide by 3 on both sides to get x alone.
3x/3= x 27/3=9
X=9
Answer:
The equation that can be use to determine the price of a sandwich is 5x + $1.25 = $38.75
Step-by-step explanation:
The equation that can be use to determine the price of a sandwich is as follows:
Let us assume the price of a sandwich be x
So,
The equation would be
5x + $1.25 = $38.75
5x = $38.75 - $1.25
x = $37.5 ÷ 5
x = $7.5
hence, the equation that can be use to determine the price of a sandwich is 5x + $1.25 = $38.75
Answer:
a = -5
b = 2
Step-by-step explanation:
a+b=-3
<u>a-b= -7</u> +
2a = -10
a = -10/2
a = -5
a + b = -3
-5 + b = -3
b = -3 + 5
b = 2
It’s C I believe
I hope it helps you with it
The simplified version is: 7z-29y+18
Hope this helps :)
