Answer:
Explanation:
(a) 2(x+4)= 12
x+4\ =\ \frac{12}{2}x+4 =
2
12
x+4 = 6
x= 6-4
x= 2
(b) 3(n-5) = 21
n-5\ =\ \frac{21}{3}n−5 =
3
21
n-5 = 7
n = 7+5
n = 12
(c) 3(n-5) = -21
n-5\ =\ -\frac{21}{3}n−5 = −
3
21
n-5 = -7
n= -7+5
n = -2
(d) 3-2 (2-y) = 7
-2 (2-y) = 7-3
-2(2-y) = 4
2-y\ =\ \frac{4}{2}2−y =
2
4
2-y = 2
-y = 2 -2
y = 0
(e) 4(2-x) = 9
-4\times2-x\times\left(-4\right)\ =\ 9−4×2−x×(−4) = 9
-8+4x = 9
4x= 9+8
x=\ \frac{17}{4}x=
4
17
