2x - 10 = 10 - 3x
Simplifying
2x + -10 = 10 + -3x
Reorder the terms:
-10 + 2x = 10 + -3x
Solving
-10 + 2x = 10 + -3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3x' to each side of the equation.
-10 + 2x + 3x = 10 + -3x + 3x
Combine like terms: 2x + 3x = 5x
-10 + 5x = 10 + -3x + 3x
Combine like terms: -3x + 3x = 0
-10 + 5x = 10 + 0
-10 + 5x = 10
Add '10' to each side of the equation.
-10 + 10 + 5x = 10 + 10
Combine like terms: -10 + 10 = 0
0 + 5x = 10 + 10
5x = 10 + 10
Combine like terms: 10 + 10 = 20
5x = 20
Divide each side by '5'.
x = 4
Simplifying
x = 4
Answer:
$90-$70=$20
Step-by-step explanation: U take 90 from 20
Hello there!
Answer:
Step-by-step explanation:
Distributive property: a(b+c)=ab+ac
First, you expand.
4(x-2)=4x-8
7x+1<4x-8
Subtract by 1 both sides of an equation.
7x+1-1<4x-8-1
Add/Subtract numbers from left/right.
8+1=9
7x<4x-9
Then, you subtract by 4x both sides of an equation.
7x-4x<4x-9-4x
Simplify equation.
3x<-9
Divide by 3 both sides of an equation.
3x/3<-9/3
Divide numbers from left/right.
-9/3=-3
<u><em>x<-3 is the final answer.</em></u>
Hope this helps!
Thanks!
