The expression (p−5+3a)−(6p−4a+1) can be rewritten in standard form.

The final answer is -5p+7a-6.

Step: (p-5+3a)+(-(6p-4a+1))

Justification: Any order, any grouping

Step: (p-5+3a)+(-6p) + 4a + (-1)

Justification: The opposite of a sum is the sum of its opposites (Subtraction as adding the opposite)

Step: p+(-6p) + 3a + 4a +(-5)+(-1)

Justification: Combine like terms

Step: (-5p) +7a+(-6)

Justification: Combine like terms

Step: -5p+7a-6

Justification: Arrange in standard form

The expression (p−5+3a)−(6p−4a+1) can be rewritten in standard form. Drag a justification to each step shown in the table.

DRAG & DROP THE ANSWER

Justification

Any order, any grouping

(p-5+3a)+(-(6p-4a+1))

The opposite of a sum is the sum of its opposites

Subtraction as adding the opposite

Combine like terms

(p-5+3a)+(-6p) + 4a + (-1)

p+(-6p) + 3a + 4a +(-5)+(-1)

(-5p) +7a+(-6)

-5p+7a-6
