Solve the equation for x by finding a, b and c of the quadratic then applying the quadratic formula
Answer:
what do you need help with which part
Step-by-step explanation:
The value of X is 11 because if you reduce the numbers with greatest common factors twice, then commutative property to record the terms, and calculate to get 11x
1. 2 (x + 3) = x - 4
2x + 6 = x- 4
2x - x = -4 - 6
x = -4 + -6 = -10.
x = 10
2. 4 (5x - 2) = 2 (9x + 3)
20x - 8 = 18x + 3
20x - 18x = 3 + 8
2x = 11
x = 11/2 = 5.5
x = 11/2 or 5.5
These are the Answers.
