Step-by-step explanation:
For equation N°2
Solving algebraically:
(Sum x on both sides of the equation)
Resolving graphically:
x = -2 --------- - (- 2) -3 = -1 pto (-2, -1)
x = -4 ---------- - (- 4) -3 = 1 pt (-4.1)
x = -3 --------- - (- 3) -3 = 0 pt (-3.0) Solution
The graphic is shown in the attached image. The red dot in the graph represents the solution
For equation N° 4
Solving algebraically:
(Sum -3 on both sides of the equation)
(divided by 9 on both sides of the equation)
(simplifies the fraction)
Resolving graphically:
x = 1 --------- 9 (1) +3 = 12 pt (1.12)
x = -1 --------- 9 (-1) +3 = -6 pto (-1, -6)
x = -1 / 3 -------- 9 (-1/3) +3 = 1 pt (-1 / 3.0) Solution
The graphic is shown in the attached image. The red dot in the graph represents the solution
For equation N°. 6.
Solving algebraically:
(Sum -4x on both sides of the equation)
The equation is not met, the x are eliminated, therefore, it has solution
For equation N°. 8
Solving algebraically:
(Sum 6x on both sides of the equation)
The x are eliminated, 3 is not equal to 5, the equality is not met. The equation has no solution.
