Solve the equation [ 2m + 3 + 4 = 12 ]

Question

trying to solve the equation of this problem [ 2m + 3 + 4 = 12  ]

Answer 1

Hi again Keith;

 2m + 3 + 4 = 12

Let's combine like terms...

2m+7=12

Let's subtract 7 from both sides...

-7+2m+7=12-7

2m=5

Let's divide both sides by 2...

(2m)/2=5/2

m=5/2

m=2.5

Let's check our work...

2m + 3 + 4 = 12

[(2)(2.5)]+3+4=12

5+3+4=12

12=12

 

 

Answer 2

m=2.5
