4x+5-10+3x=57
2 answers:
So we have to simplify this equation:
4x+5-10+3x=57
Add like terms:
7x-5=57
Then add 5 to both sides:
7x=62
x=62/7
Answer:
4x+5-10+3x=57
Simplifying
4x + 5 + -10 + 3x = 57
Reorder the terms:
5 + -10 + 4x + 3x = 57
Combine like terms: 5 + -10 = -5
-5 + 4x + 3x = 57
Combine like terms: 4x + 3x = 7x
-5 + 7x = 57
Solving
-5 + 7x = 57
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '5' to each side of the equation.
-5 + 5 + 7x = 57 + 5
Combine like terms: -5 + 5 = 0
0 + 7x = 57 + 5
7x = 57 + 5
Combine like terms: 57 + 5 = 62
7x = 62
Divide each side by '7'.
x = 8.857142857
Simplifying
x = 8.857142857

Answer:
-30
Step-by-step explanation:
-|-30-(10-20)|-|5-(10-15)|=-|-30-(-10)|-|5-(-5)|
=-|-30+10|-|5+5|
=-|-20|-|10|
=-(20)-(10)
= -20-10
= -30
