Question

Given that 9x=28-5x.find the value of x
​

Answer 1

`~~~~9x=28-5x\\\\\implies 9x +5x = 28\\\\\implies 14x = 28\\\\\implies x = (28)/(14)\\\\\implies x = 2`

Answer 2

Explanation:

Given Equation,

`\\ \longrightarrow \qquad \sf 9x=28-5x \\ \\`

Now, Adding 5x to both sides we get :

`\\ \longrightarrow \qquad \sf 9x + 5x=28-5x + 5x \\ \\`

`\longrightarrow \qquad \sf 14x=28 \\ \\`

Dividing 14 from both sides we have :

`\\ \longrightarrow \qquad \sf (14x)/( 14 ) = (28)/(14) \\ \\`

`\longrightarrow \qquad \sf x=2 \\ \\`

Therefore,

• The value of x is 2
