Step 1: Define Systems

-x + 4y = -8

-5x - 4y = -16

Step 2: Solve for x

Elimination

Combine equations: -6x = -24
Isolate x: x = 4

Step 3: Solve for y

Define equation: -x + 4y = -8
Substitute in x: -4 + 4y = -8
Isolate y term: 4y = -4
Isolate y: y = -1

Solve the following equation: |7 – (24 ÷ | 3-6 |)| (A)15(B)-12(C)1(D)-1

Zepler [3.9K]

PEDMAS

The rule is Paranthesis First

|7-(24÷|3-6|)|

|7-(24÷|-3|)|

Now we have to get the -3 outside the 2 Lines but the lines are saying that if the number inside is negative when you get it outside it has to be positive.

|7-(24÷3)|-

|7-(8)|

|7-8|
