Question

2x+3x+4x=180
9x=180
x=20

how did they get 20, am i missing something

Answer 1

Answer: ❤️Hello!❤️ x = 20

Step-by-step explanation: Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

2*x+3*x+4*x-(180)=0

Step 1 :

Pulling out like terms :

1.1 Pull out like factors :

9x - 180 = 9 • (x - 20)

Step 2 :

Equations which are never true :

2.1 Solve : 9 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2 Solve : x-20 = 0

Add 20 to both sides of the equation :

x = 20

Answer 2

♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫

➷ We'll work from here:

9x = 180

To isolate x, you would need to divide both sides by 9

x = 180/9

Solve:

x = 20
