25 + 10(12 + -1x) = 5(2x + -7)
25 + (12 * 10 + -1x * 10) = 5(2x + -7)
25 + (120 + -10x) = 5(2x + -7)
Combine like terms: 25 + 120 = 145
145 + -10x = 5(2x + -7)
Reorder the terms:
145 + -10x = 5(-7 + 2x)
145 + -10x = (-7 * 5 + 2x * 5)
145 + -10x = (-35 + 10x)
Solving
145 + -10x = -35 + 10x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-10x' to each side of the equation.
145 + -10x + -10x = -35 + 10x + -10x
Combine like terms: -10x + -10x = -20x
145 + -20x = -35 + 10x + -10x
Combine like terms: 10x + -10x = 0
145 + -20x = -35 + 0
145 + -20x = -35
Add '-145' to each side of the equation.
145 + -145 + -20x = -35 + -145
Combine like terms: 145 + -145 = 0
0 + -20x = -35 + -145
-20x = -35 + -145
Combine like terms: -35 + -145 = -180
-20x = -180
Divide each side by '-20'.
x = 9
Simplifying
x = 9.

Answer:
Can you maybe elaborate the question with the help of brackets I guess ...?
It is difficult to understand the question this way .
Answer:
a = 35°
Step-by-step explanation:
The angles in a triangle always add up to 180°
∴ 33 + 112 + a = 180
∴a=35°
Answer:
52
Step-by-step explanation:
You already said that DE=52.
(12x3 - 14x2 - 40x) / (2x-5)
Rewriting we have:
(2x (2x-5) (3x + 4)) / (2x-5)
We simplify similar terms:
2x * (3x + 4)
We rewrite:
6x2 + 8x
Answer:
The simplified expression is given in this case by:
6x2 + 8x
