Transpose the (2) on the other side para mag-isa nalang yung x. Then, change mo yung sign ng (2) na magiging negative na siya. Ganito dapat kinalabasan:
x = 6 - 2
Then, subtract mo nalang siya.
x = 4
2. x + 7 = -3
Transpose mo yung (7) on the other side, and as always so that the (x) will be alone. Then, change mo yung sign ng (7) na magiging negative na siya imbes na positive. So dapat kinalabasan niyan:
x = -7 - 3
If medyo nahihirapan ka sa pag-subtract ng parang ganyan, eto yung ginagawa ko.
- I-add mo lang sila, parang sa pag-add ng positive numbers. But, negative sign yung kakalabasan ng resulta.
x = -10
3. 6 + x = 9
Again, transpose the (6) to the other side, it will be negative or have operation of subtraction dahil positive siya noong original position siya. So, dapat magiging ganito kinalabasan:
x = 9 - 6
Then, simply subtract the two numbers and this will be the result.
x = 3
4. 2x + 4 = 10
Transpose mo yung (4) to the other side, it will be negative since its original sign was positive. Then dapat magiging ganito yung kinalabasan:
2x = 10 - 4
Then, subtract mo yung (10) sa (4).
2x = 6
Since what you have observed na yung coefficient ng x ay greater than 1, then i-cancel mo by dividing both sides by 2 since yan yung coefficient niyan.
.Then simplify mo na sila by dividing both by 2 as given above.
x = 3
5. -2x - 5 = 7
Transpose mo yung (-5) in the other side. In this case, since negative yung (-5), magiging positive na siya sa other side. Dapat ganito kinalabasan :
-2x = 7 + 5
Simplify by adding the (7) and (5).
-2x = 12
Then, in this case, i-divide mo sila both sides by (-2) para macancel coefficient. Since negative yung sign ng coefficient, i-change mo yung sign ng both sides by their opposite signs.
Answers & Comments
Answer:
1. x = 4
2. x = -10
3. x = 3
4. x = 3
5. x = -6
Step-by-step explanation:
EXPLANATIONS :
1. x + 2 = 6
x = 6 - 2
x = 4
2. x + 7 = -3
x = -7 - 3
- I-add mo lang sila, parang sa pag-add ng positive numbers. But, negative sign yung kakalabasan ng resulta.
x = -10
3. 6 + x = 9
x = 9 - 6
x = 3
4. 2x + 4 = 10
2x = 10 - 4
2x = 6
x = 3
5. -2x - 5 = 7
-2x = 7 + 5
-2x = 12
x = -6
Sana makatulong!
