Answer:

x < 5

Explanation:

  • Add 3 to both sides of the equation. This is to balance the equation.

2x - 3 + 3 < 7 + 3

  • Now, add 7 and 3.

7 + 3 = 10

  • Add -3 and positive 3.

-3 + 3 = 0

= 2x + 0

= 2x

  • Now, the problem becomes,

2x < 10

  • Divide by 2

2x/2 < 10/2

  • Divide by 2: 10/2

10/2 = 5

  • Divide by 2: 2x

2x/2 = 2/2

= x (We assume x = 1)

  • Divide both numbers

= 5/1

= 5

Therefore,

x < 5

Hope this helps!
