Answer:6
Step-by-step explanation:
I'll do one, you can use it as a basis for your answer.
Subtract 6 from both sides to get X by itself.
Now we divide by 7 for both sides as well.
Now we find the square root of 1 to figure out X.
Therefore, X=1.

Answer:
Step-by-step explanation:
3x - 4y = -11
x - 2y = -5
Compare the coefficients of the variables.
The coefficients of the x terms, 3 and 1, are multiples of each other.
The coefficients of the y terms, -4 and -2, are also multiples of each other.
That makes it easy to eliminate either variable.
I'll eliminate the y variables. Multiply the second equation by -2, then add it to the first equation:
₋-2x + 4y = 10
3x - 4y = -11
--------------------
x + 0y = -1 , so x = -1.
Substitute -1 for x in either equation and solve for y:
3(-1) - 4y = -11
y = 2
(x,y) = (-1, 2)
Remember
(ab)/c=a(b/c)
and
b/b=1 when b=b
1.
8+9t+4=
8+4+9t=
12+9t=
9t+12
2. (56ab)/b=56a(b/b)=56a(1)=56a
3. divising negatives yeilds positive
-46/-2=46/2=23
