Question

What value of x makes the two expressions equal (image)

Answer 1

`\sf \: x = 6.5`

Explanation:

Given expressions,

→ 7x - 5

→ 5x + 8

Now we have to,

→ Find the required value of x.

Forming the equation,

→ 7x - 5 = 5x + 8

Then the value of x will be,

→ 7x - 5 = 5x + 8

→ 7x - 5x = 8 + 5

→ 2x = 13

→ x = 13 ÷ 2

→ [ x = 6.5 ]

Hence, the value of x is 6.5.

Answer 2

`\huge\boxed{\sf x = 6.5 }`

Explanation:

Given that, both the expressions are equal.

So,

7x - 5 = 5x + 8

• Subtract 5x from both sides

7x - 5x - 5 = 8

2x - 5 = 8

• Add 5 to both sides

2x = 8 + 5

2x = 13

• Divide both sides by 2

x = 13/2

x = 6.5
