Question

1) 2(a + 3) = -12

Answer 1

1)
2(a + 3) = -12
Divide by 2
a + 3 = -6
Subtract 3
a = -9

2)
3(p + 2) = 18
Divide by 3
p + 2 = 6
Subtract 2
p = 4

3)
4(2r + 8) = 88
Dive by 4
2r + 8 = 22
Subtract 8
2r = 14
Divide by 2
r = 7

4)
2(3a + 2) = -8
Divide by 2
3a + 2 = -4
Subtract 2
3a = -6
Divide by 3
a = -2

5)
4(k + 3) = 4
Divide by 4
k + 3 = 1
Subtract 3
k = -2

Answer 2

Answer:

1)-9 2)4  3)7  4)-2 5) -2

Step-by-step explanation:

1) 2(a+3)=-12            2) 3(p+2)=18             3) 4(2r+8)=88          4) 2(3a+2)=-8

2a+6=-12                    3p+6=18                   8r+32=88                6a+4=-8

-12-6=-18                   18-6                            8r=56                       -8-4=-12

2a=-18     18/2                  3p=12  12/3         56/8                       6a=-12   -12/6

a=-9                           p=4                            r=7                           a=-2
