Question

Me ayudan porfavor?

6 (b + 5) = 18
-7 (h - 4) = 21
2 (3 - t) = -10
4 (x + 5) = 36
6 (a + 5) = 42
4 (6 - x) = 20

Answer 1

6 (b + 5) = 18
6b + 30 = 18
6b = 18 - 30
6b = -12
b = -12/6
b = -2

-7 (h - 4) = 21
-7h + 28 = 21
-7h = 21 - 28
-7h = -7
h = -7/-7
h = 1

2 (3 - t) = -10
6 - 2t =-10
-2t = -10 -6
-2t = -16
t = -16/-2
t = 8

4 (x + 5) = 36
4x + 20 = 36
4x = 36 -20
4x = 16
x = 16/4
x = 4

6 (a + 5) = 42
6a + 30 = 42
6a = 42 -30
6a = 12
a = 12/6
a = 2

4 (6 - x) = 20 
24 - 4x = 20
-4x = 20 - 24
-4x = -4
x = -4/-4
x = 1
