Answer:
x=5
Step-by-step explanation:
11-7= 4
The distance is 4 units.
X² + 20 = 4
x² = 4 - 20
x² = -24 ⇒ no real number solutions
Answer:
The equation: 3 + x = 7. will be false if any number except 4 is substituted for the variable. The value of the ... Example 2 Find the solution of each equation by inspection. a. x + 5 = 12 b. 4 · x = -20 ... 3x + 3 = x + 13, 3x = x + 10, 2x = 10, and x = 5.
