First equation is: x - y = 12
x = 12 + y

Now, substitute this in 2nd equation, 
2x - 3y = 27
2(12+y) - 3y = 27
24 + 2y - 3y = 27
-y = 27 - 24
y = -3

In short, Your Answer would be -3

Hope this helps!

Best Method using system of equations<br><br><br> x=4y+8<br> 2x-8y=-3
Mkey [24]
In this case, since one equation is in the form of x=, substitution would be best for this problem.  Simply plug in 4y + 8 in place of x in the second equation, solve for y, then plug that value into the first equation to find x.

in a right angled triangle if the hypotenuse is 15 cm and the ratio of the other two sides is 3:4 find the measures of the right
wariber [46]

Answer:

the other sides are 9 and 12

Step-by-step explanation:

use the Pythagorean theorem.

a^{2} +b^{2} =c^{2}

you know that c^2 is 225 because 15*15=225

a^{2} +b^{2} =225

(from here on I just plugged numbers in)

3:4=9:12

9^{2} +12^{2} =225

81+144=225

225=225

Yaaaaay!
