Question

Match the justification to each statement in the solution of x + 12.7 = -25.2.

Answer 1

1) x+12.7=-25.2 is given

2)x+12.7-12.7=-25.2-12.7 is the subtraction property of equality(subtracting on both sides)

3)x+0=-37.9(add. inverse/simplification since we're simplifying the equation)

x=-37.9(identity property of addition since x+0 is just x)

Hope this helps!
