Question

3(x+7)-2(x-1)=11 solve the equation and check the result

Answer 1

Answer:

3x+21-2x+2=11

x+23=11

x= -12

checking

3(-12+7)-2(-12-1)

3×-5+26

11

Answer 2

Answer:

Step-by-step explanation:

=> 3x+21-2x+2 = 11

=> 3x-2x+21+2 = 11

=> x+23 = 11

=> x = 11-23

=> x = -12

Verify:

=> 3(-12+7)-2(-12-1) = 11

=> 3(-5)-2(-13) = 11

=> -15+26 = 11

=> 11 = 11
