Question

Q.Solve the following equations and check the solutions. (a) 1-4x=-11. (b) y+3/2 = 5 please answer me fast. ​

Answer 1

Answer:

(i) 3,(ii)7/2

Step-by-step explanation:

(i) 1-4x=-11

-4x= -11-1

-4x= -12

we cut minus to minus then 4x= 12

x= 12/4= 3

We will check solution we put the value of x is 3.

1-4(3)= -11

1-12= -11

-11= -11

L.H.S=R.H.S

(ii) y+3/2= 5

y= 5/1 - 3/2

y= 7/2

if we check we take y=7/2

7/2+3/2=5

10/2=5

5=5

L.H.S=R.H.S
