The expression that is not equivalent is - 2x -0.5 + 6 y + 3 x
Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value(s) for the variable(s).
Given the expression -3x - 0.5 + 4y
We are to get the equation equivalent to the expression
2y - 5x - 0.5 + 2y + 2x
4y -3x - 0.5
Hence, the equations are equal
For the expression -2 x -0.5 + 6 y + 3 x
This is equivalent to x + 6y - 0.5
Hence , the expression that is not equivalent is -2 x -0.5 + 6 y + 3 x
