Solve using transposition method:
a) 1 – 4 x = -11
b) 3 p = 12
c) 4( 2 – x ) = 20
d)
5
+ 3 = 7
Answers
Step-by-step explanation:
a) 1 - 4x = -11
4x = -11 + 1
4x = -10
x = -10/4
x = -2.5
b) 3p = 12
p= 3/12
p= 4
c) 4 (2 - x) = 20
(2 - x) = 20/5
(2 - x) = 4
2 = 4 + x
2 - 4 = x
-2 = x
d) x/5 + 3 = 7
x/5 = 7 - 3
x/5 = 4
x = 5 × 4
x = 20

a) 1 – 4 x = -11
⇒4x = 1 + 11
⇒4x = 12
⇒x = 12/4
⇒x = 3
--------------------------------------
b) 3 p = 12
⇒p = 12/3
⇒p = 4
--------------------------------------
c) 4( 2 - x ) = 20
8 - 4x = 20
⇒8 - 20 = 4x
⇒4x = -12
⇒x = -12/4
⇒x = -3
--------------------------------------
d) x/5+3=7
⇒x/5 = 7-3
⇒x/5 = 4
⇒x = 4 × 5
⇒x = 20
