Question 950716: H+b=122
14h+2=b
Answer by addingup(3677)   (Show Source):
You can put this solution on YOUR website! H+b=122 therefore h= 122-b
14h+2=b Let's substitute the value of h, per above information:
14(122-b)+ 2 = b Multiply on the left
1708 - 14b + 2 = b Add numbers on left, and add 14b to both sides
1710 = 15b Flip the numbers so we have the b on the left (it changes nothing)
15b = 1710 Divide both sides by 15
b = 1710/15 = 114 OK, and we said h= 122 - 114 = 8
Now let's see if we've got the right number, the second equation will tell:
14h+2=b, and since b= 114:
14h+2= 114 Let's plug in the value of h, which we just said is 8:
14(8)+2=114 Do the math and you get:
112+2= 114
114 = 114 We've got the correct answers.
