Answer:
True
Step-by-step explanation:
An integer is anything that's not a fraction/decimal, and being even is common knowledge
You can show it 4 ways by rotating the paper and if that is not an option, then the answer is 2.
Method One
You could divide by 5 right away.
20/5 = - 3 + x
4 = - 3 + x Add 3 to both sides.
4 + 3 = x
x = 7
Method Two.
You could remove the brackets. This is slightly longer, but some questions can only be solved that way.
20 = 5(-3) + 5x
20 = -15 + 5x Add 15 to both sides
20 + 15 = 5x
35 = 5x Divide by 5
35/5 = x
7 = x
