Question

Can someone tell me how to solve these questions step by step

Answer 1

For the given linear equations we have:

a) for 5 + t = 23, the solution is t = 18

b) for -7 + b = -8, the solution is b = -1

c) for 5q = -75, the solution is q = -15.

How to solve the linear equations?

Here we have some linear equations.

The first one is:

5 + t = 23

To solve this, we need to isolate the variable in one side of the equation. Remember that we can do the same operation in both sides of the equation, and the equation keeps being the same one.

Then, here we can subtract 5 in both sides so get:

5 + t - 5 = 23 - 5

t = 23 - 5

t = 18

The solution here is t = 18.

b) The second linear equation is:

-7 + b = -8

Again, we want to isolate b, so we can just add 7 in both sides so we get.

-7 + b + 7 = -8 + 7

b = -8 + 7 = -1

b = -1

The solution to this linear equation is b = -1

The last one is:

5q = -75

Here we need to isolate q, so we can divide both sides by 5.

5q/5 = -75/5

q = -75/5 = -15

The solution here is q = -15.
