If we assume the age of Francos is x, then dad will be 3x
In 10 years
Francos = x+10
Dad    = 3x+10
Therefore, 3x+10 =2(x+10)+2
                  3x +10 = 2x+20+2
                           x = 22-10
                            x =12 
Therefore, the present ages will be
Francos = 12 years
 Dad      = 36 years

Let

Y
 be the age of Franco's dad.
X  Franco's age

Y = 3*X                           (1)
(Y +10) = 2*(X+10) +2            (2
)


(3*X  +10) = 2*X +20 +2   

(3-2)X = 22 -10

X = 12 years old  (Franco)

Y = 3*12 = 36 years old (Franco's dad)

Solve the linear system of equations using the linear combination method.<br><br> {8a−4b=205a−8b=62
11Alexandr11 [23.1K]
Sorry I am a little late...

a = -2

b = -9

Here is how to solve the problem. 

First thing I did was multiply the first equation by -2 so that we can eliminate the the b. After you multiply it by -2, your new equation is -16a + 8b = -40. 

You leave the second equation alone and all you do is combine like terms. So -16a+5a is -11. And you eliminate the b. Then you're going to do -40+62 which is 22. So it's -11a=22 and then you have to solve for a. What I did was I multiplied the whole thing by minus to turn the a positive. So then it's 11a=-22. Pretty easy, the final step is to simplify. -22/11 is -2. ;D 

So there you have your first answer. 

a = -2 

Now we're going to use the first answer to help us find b. 

For the second equation, all you're going to do is plug in that a. 

5 (-2)-8b=62 

-10 - 8b = 62

Now we move the -10 to the other side...

-8b = 62 + 10 

-8b = 72

Multiply the whole thing by negative once again to turn the b positive.

Now we have 8b = -72 

The final step is to simplify. -72/11 = -9

b = -9 

Hope this makes sense! Also I had the same question on my test and I got it right. :)

<span>3/8 ÷ 0.5 = 3/4 
2.5 ÷ 18/8 = 2/5 

Since 3/4 > 2/5, he has too much milk. He'll get runny pancakes.Hope this helps! =)</span>
