A = 2 + 3a + 6
a - 3a = 2 + 6
-2a = 8
a = 8/-2
a = -4

The answer is to your question is 192817359
Answer:
Q1. 20x = 200. The value of x is 10
Q2. 7 - 3x = 1. The value of x is 2.
Step-by-step explanation:
In order to find an equation, you have to let the number be any variable, such as m or n or z. So I will let the number be <em>x variable</em>. Then the question says a number is multiplied by 20 is equals to 200 :
Let number = x,




Same for the next question. Given that a number multiplied by 3 :
Let number = x,

Then subtracted by 7 equals to 1 :
