To solve the equation −3x − 9 = −21, we can follow these steps:
1. Start with the equation: −3x − 9 = −21.
2. Group the terms containing x on one side of the equation. To do this, we can add 9 to both sides: −3x - 9 + 9 = -21 + 9.
Simplifying, we get: -3x = -12.
3. Divide both sides by -3 to isolate x. So, -3x / -3 = -12 / -3.
Simplifying further, we have: x = 4.
So, the solution to the equation −3x − 9 = −21 is x = 4.
Similarly, to solve the equation 10x + 13 = −12, we can follow these steps:
1. Start with the equation: 10x + 13 = −12.
2. Group the terms containing x on one side of the equation. To do this, we can subtract 13 from both sides: 10x + 13 - 13 = -12 - 13.
Simplifying, we get: 10x = -25.
3. Divide both sides by 10 to isolate x. So, 10x / 10 = -25 / 10.
Simplifying further, we have: x = -2.5.
So, the solution to the equation 10x + 13 = −12 is x = -2.5.
For the equation 5 − 6x = −7 , we can solve it as follows:
1. Start with the equation: 5 − 6x = −7.
2. Group the terms containing x on one side of the equation. To do this, we can subtract 5 from both sides: 5 - 6x - 5 = -7 - 5.
Simplifying, we get: -6x = -12.
3. Divide both sides by -6 to isolate x. So, -6x / -6 = -12 / -6.
Simplifying further, we have: x = 2.
So, the solution to the equation 5 − 6x = −7 is x = 2.
