Question

what is the answer of 2x+3x+5=20​

Answer 1

Answer:

X=3

Step-by-step explanation:

2x+3x+5=20

firstly, we must do the sum of same variables so,

5x+5=20

now,

5x=20-5

5x=15

X=15/5

X=3

Answer 2

Simplifying

2x + 3x + -5 = 20

Reorder the terms:

-5 + 2x + 3x = 20

Combine like terms: 2x + 3x = 5x

-5 + 5x = 20

Solving

-5 + 5x = 20

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 + 5x = 20 + 5

Combine like terms: -5 + 5 = 0

0 + 5x = 20 + 5

5x = 20 + 5

Combine like terms: 20 + 5 = 25

5x = 25

Divide each side by '5'.

x = 5

Simplifying

x = 5
