II. Solve each equation and check your solution. Write your answer at the back of your test questionnaire. (5pts each)
1. x + 4 = -5
2. a + 13 = 20
3. b-16=-7
4.4g - 7 = 5g - 15
5.e-(-3) = -6

Solve each equation and check your solution. Write your answer at the back of your test

given⬇️⬇️

1. x + 4 = -5

2. a + 13 = 20

3. b-16=-7

4.4g - 7 = 5g - 15

5.e-(-3) = -6

answer:⬇️⬇️

1 x=-5

2 a=7

3 b=9

4 g=0.9375

5 e=-3

solution⬇️⬇️

$1 = > x + 4 = - 2 \\ = > - 4 \: \: - 4 \\ = > x = - 2 \\ \\ \\ 2. = > a + 13 = 20 \\ = > - 13 \: \: \: - 13 \\ = > a = 7 \\ \\ 3. = > b - 16 = - 7 \\ \: = > + 16 \: \: \: + 16 \\ = > b = 9 \\ \\ 4 = > 4g - 7 = 5g - 15 \\ = > + 7 \: \: \: + 7 \\ = > 4g + 12g - 15 \\ = > \frac{16g}{16} = \frac{15}{16} \\ = > g=0.9375 \\ \\ 5. = > e - ( - 3) = - 6 \\ = > + 3 \: \: + 3 \\ = > e = - 3$
