Answer 1

Answer:

1.) b - We have to subtract 1 to both the side of given equation,

Then we get,

= x + 1 – 1 = 0 – 1

= x = – 1

1.) f - We have to add 4 to both the side of given equation,

Then we get,

= y – 4 + 4 = 4 + 4

= y = 8

Step-by-step explanation:

2.) h- Now we have to divide both sides of the equation by 20,

Then we get,

= 20t/20 = -10/20

= x = – ½

Answer 2

Answer:

Step-by-step explanation:

X is a variable so that you have to make x to an no. 1 then solve the problem
