4x -1 3x + 2
Answers
Simplifying
5x + 6 = 2x + -3
Reorder the terms:
6 + 5x = 2x + -3
Reorder the terms:
6 + 5x = -3 + 2x
Solving
6 + 5x = -3 + 2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2x' to each side of the equation.
6 + 5x + -2x = -3 + 2x + -2x
Combine like terms: 5x + -2x = 3x
6 + 3x = -3 + 2x + -2x
Combine like terms: 2x + -2x = 0
6 + 3x = -3 + 0
6 + 3x = -3
Add '-6' to each side of the equation.
6 + -6 + 3x = -3 + -6
Combine like terms: 6 + -6 = 0
0 + 3x = -3 + -6
3x = -3 + -6
Combine like terms: -3 + -6 = -9
3x = -9
Divide each side by '3'.
x = -3
Simplifying
x = -3
4*x-((3*x)/2) = 20 // - 20
4*x-((3*x)/2)-20 = 0
4*x+(-3/2)*x-20 = 0
5/2*x-20 = 0 // + 20
5/2*x = 20 // : 5/2
x = 20/5/2
x = 8
x = 8
Answer:
I'll take the answer as you multiplying them so-
Step-by-step explanation:
(5x-6)(2x+3)
cross multiplication-
10x^2 + 15x - 12x - 18
10x^2 - 18 + 7x
and for the second one-
(4x -1)(3x + 2)
12x^2 + 8x - 3x -2
12x^2 - 2 +5x
if this is not your Question let me know I'll tell you ^^
if yes, please mark as brainliest.
