Question

Solve the given equations 1) -4 (2 - x ) = 8 2) 3 ( y - 5) = 21​

Answer 1

Answer:

1) x = 4

2) y = 12

Step-by-step explanation:

1) -4(2 - x) = 8

transpose -4 from L.H.S to R.H.S...

then,

2 - x = 8/-4

2 - x = -2

transpose 2 from L.H.S to R.H.S...

we get,

-x = -2-2

-x = -4

cancel minus on both sides...

x = 4

2) 3(y-5) = 21

transpose 3 from L.H.S to R.H.S...

then,

y - 5 = 21/3

y - 5 = 7

transpose -5 from L.H.S to R.H.S...

y = 7 + 5

y = 12
