Use the algebra tiles to model the equation 2x + 4 = 3x + (−1). Then complete the sentences. To model 2x + 4, you need:
melomori [17]

The value of x would be 5 for the model 2x+4.

Rearrange unknown terms to the left side of the equation,
= > 2x-3x = -1 - 4

Combine like terms= -x = -1-4

By calculating the sum or difference : -x = -5

Lets divide both sides of the equation by the resulting coefficient 5
So x = 5
