form 4 different Equations

2. The solution is x = 2

form 4 different Equations​

Answer 1

1.)

Answer: 30

Step-By-Step Explanation:

Let the required number be x.

According to the given data, it seems to be a linear equation in x

Seven times the number gives 7x

Adding a fifty to that number gives 7x + 50 ____ (1)

To reach a triple century means the above equation needs to be equated to 300

Still forty is required for it to be equated to 300

7x + 50 = 300 – 40

7x +50 + 40 = 300

7x + 90 = 300

7x = 300 – 90 = 210

7x = 210

x = 210/7

x = 30

2.)

Answer:3

Step-By-Step Explanation:

3×5 = 15

15-5 = 10

1.)

Answer:

(x+2=7)

(x-2=3)

(x×2=10)

(x÷5=1)

2.)

Answer:

(x+25=29)

(x-3=1)
