Question

(x+37):4=79   /  6x-2x+4 =40  /  3X^2+2=77 / 3 (x - 5)+x =33 / x+5=26-2x / X^5 - 1= 31

Answer 1

1. (x + 37)/4 = 79
x + 37 = 316
x = 278

2. 6x - 2x + 4 = 40
4x = 36
x = 9

3. 3x^2 + 2 = 77
3x^2 = 75
x^2 = 25
x = 5

4. 3(x - 5)+ x = 33
3x - 15 + x = 33
4x = 48
x = 12

5. x + 5 = 26 - 2x
3x = 21
x = 7

6. x^5 - 1 = 31
x^5 = 30
x = raíz quinta de 30

Answer 2

1ra: x=42 
2da: x=9
3ra: x=5
4ta: x=12
5ta: x=7
