- » We can say that the solution set of this equation of the first degree is equal to: S = {3}.
● With the indicated equation:
[tex] \: \boxed{10 × 10 = 40} [/tex]
● Method to calculate:
- » To solve this equation of the first degree, we will isolate "10x" to the right side of the equality, and we will move the positive number +10 to the other side of the equality by subtracting. Next, let's isolate "x" and finally divide both sides of the equation between each other.
[tex]10x + 10 = 40[/tex]
[tex]10x = 40 - 10[/tex]
[tex]10x = 30[/tex]
[tex]x = \frac{30}{10} [/tex]
[tex]x = 3[/tex]
[tex] \: \boxed{S = 3} √[/tex]
[tex]−−−−−−−✠−−−−−−−[/tex]
