please give me answer fast ​

Answer 1

Answer:

1. x=7-2 =5
2. x=8+3= 11
3. A=6+3 = 9
4. n=30/6 = 5
5. q=25/5= 5
6. z=18/3= 6

Answer 2

$\huge\textbf\color{blue}{Answer}$

1.

$x + 2 = 7 \\ = > x = 7 - 2 = 5 \\ = > x = 5$

2.

$x - 3 = 8 \\ = > x = 8 + 5 = 13 \\ = > x = 13$

3.

$a - 3 = 6 \\ = > a = 6 + 3 = 9 \\ a = 9$

4.

$6n = 30 \\ = > n = 30 \div 6 = 5 \\ = > n = 5$

5.

$5q = 25 \\ = > q = 25 \div 5 = 5 \\ = > q = 5$

6.

$3z = 18 \\ = > z = 18 \div 3 = 6 \\ = > z = 6$

Hope it helps.
