3(x+5)=8x+14-3(2x-1
solve the equation
Answers
Answer:
Simplifying
3(x + 5) = 8x + 14 + -3(2x + -1)
Reorder the terms:
3(5 + x) = 8x + 14 + -3(2x + -1)
(5 * 3 + x * 3) = 8x + 14 + -3(2x + -1)
(15 + 3x) = 8x + 14 + -3(2x + -1)
Reorder the terms:
15 + 3x = 8x + 14 + -3(-1 + 2x)
15 + 3x = 8x + 14 + (-1 * -3 + 2x * -3)
15 + 3x = 8x + 14 + (3 + -6x)
Reorder the terms:
15 + 3x = 14 + 3 + 8x + -6x
Combine like terms: 14 + 3 = 17
15 + 3x = 17 + 8x + -6x
Combine like terms: 8x + -6x = 2x
15 + 3x = 17 + 2x
Solving
15 + 3x = 17 + 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.
15 + 3x + -2x = 17 + 2x + -2x
Combine like terms: 3x + -2x = 1x
15 + 1x = 17 + 2x + -2x
Combine like terms: 2x + -2x = 0
15 + 1x = 17 + 0
15 + 1x = 17
Add '-15' to each side of the equation.
15 + -15 + 1x = 17 + -15
Combine like terms: 15 + -15 = 0
0 + 1x = 17 + -15
1x = 17 + -15
Combine like terms: 17 + -15 = 2
1x = 2
Divide each side by '1'.
x = 2
Simplifying
x = 2
