Question

EXERCISE 9B
Solve each of the following equations and verify the answer in each case:
1. X + 5 =12
2. X + 3 = -2
3. X - 7 = 6
4. x - 2 = -5
5. 3x - 5 = 13​

Answer 1

1. X+5=12
2. X+3=-2
3. X-2=6
4. X-2=-5
5. 3X - 5=13

Answer 2

$\huge\fbox\pink{Answer}$

$I)X + 5 =12$

$X=12-5$

$X=7$

$2)X+3= -2$

$X= -2-3$

$X= -5$

$3)X-7=6$

$X=6+7$

$x=13$

$4)X-2=-5$

$X= -5+2$

$X=-3$

$5)3x-5=13$

$3X=13+5$

$3x=18$

$X=18/3$

$X=6$
