Question

construct 3 equation starting with x = 7

Answer 1

Given, x=7

1) x-4=3
⇒7-4=3

2)7x=49
⇒7*7=49

3)x+2=9
⇒7+2=9

Answer 2

The equations will be 2x = 14, 3x + 10 = 31, and 5x – 8 = 27.

Given:

X = 7

To Find:

Three equation using x = 7

Solution:

It's fairly simple to find the answer to this question, as seen below.

It is given that x should be equal to 7

Equation 1:

We have x = 7

Multiply both sides of the equation with 2 then,

2x = 14

Hence,

x = $\frac{14}{2}$

x = 7

Hence, the equation is 2x = 14

Equation 2:

We have x = 7

Multiply both sides of the equation with 3,

That is,

3x = 21

Then adding 10 on both sides of the equation,

3x + 10 = 21 + 10

3x + 10 = 31

3x = 31 – 10

3x = 21

X = $\frac{21}{3}$

X = 7

Hence, the equation is 3x + 10 = 31

Equation 3:

We have x = 7

Multiplying both sides of the equation with 5,

That is,

5x = 35

Subtracting 8 from both sides of the equation,

5x – 8 = 35 – 8

5x – 8 = 27

5x = 35

X = $\frac{35}{5}$

X = 7

Hence, the equation is 5x – 8 = 27
