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
Answer:
D or 6.4
Step-by-step explanation:
-6.3*(-2) + 2(-2 - 1.1)
- 6.3 * - 2 = 12.6 Notice that the two minus signs become a +
(-2 - 1.1)= (-3.1) Multiply -3.1 * 2 = - 6.2
12.6 - 6.2 = 6.4
