Question

Find the value of x: 3 (x + 2) – 2 (x – 1) = 7​

Answer 1

Answer:

-1

Step-by-step explanation:

3 (x + 2) – 2 ( x–1) =7

3x + 6 – 2x + 2 = 7

(3x –2x) + 6 + 2 = 7

x +8 = 7

x = 7–8

x = –1

Answer 2

Answer: The value of x=-1

Step-by-step explanation:

Given, 3(x+2)−2(x−1)=7

We have to find out the x value

3x+6−2x+2=7

x+8=7

x=7-8

x=-1

Thus we get the value of x=-1

To check the equation putting x=-1

3 (x + 2) – 2 (x – 1)

3(-1+2)-2(-1-1)

3(1)-2(-2)

3-(-4)=7

Hence proved x=-1
