Question

Solve 2(5x-5)=40
High School Mathematics

Answer 1

Simplifying
2(5x + -5) = 40

Reorder the terms:
2(-5 + 5x) = 40
(-5 * 2 + 5x * 2) = 40
(-10 + 10x) = 40

Solving
-10 + 10x = 40

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '10' to each side of the equation.
-10 + 10 + 10x = 40 + 10

Combine like terms: -10 + 10 = 0
0 + 10x = 40 + 10
10x = 40 + 10

Combine like terms: 40 + 10 = 50
10x = 50

Divide each side by '10'.
x = 5

Simplifying
x = 5

Answer 2

x=5

Explanation:

first you distribute so its

2 x 5x =10x

2 x 5 =10

so its now 10x -10=40

the you do the opposite of subtraction with the 10 so its +10 to the 40 which is 50

now ur left with 10x=50

you do the opposite of mulitpication which is division so u divide both sides by 10 and you get x=5
