Answer:
X=7 and y=6
Step-by-step explanation:
Y=-2x + 20.......eq(i)
6x-5y=12.....eq(ii)
Now, putting y= - 2x +20 in eq (ii)
6x - 5(-2x + 20)=12
6x + 10x - 100 = 12
16x=12+100
X=112 /16
X=7
Then, putting x=7 in eq (i)
Y=-2*7 +20
=-14 +20
=6
This question is incomplete because the options are missing. Here are the options:
A. - 4 = 5x
B. -4 = x
C. -4 + x = 0
D. -4 + 5x = 0
The correct next line of the solution is A. -4 = 5x
An equation is:
- A mathematical expression that represents mathematical equality between two expressions.
- It has two expressions and is separated by the equal sign, called members.
- It has known elements and unknown or unknown data represented with letters like x
According to the above, it can be inferred that the correct answer is option A. because it expresses the correct values according to the operations that have been carried out in the previous lines.

Answer:
m = 7, m = -15
Step-by-step explanation:
The absolute value makes it so we can make two equations:
m + 4 = 11 and m + 4 = -11.
solve the equations:
m + 4 = 11
m = 7
and
m + 4 = -11
m = -15.
