Answer:
2x - 2y = 14
x - y = 2
1.) x = 2+ y
2.) 2(2+ y) - 2y = 14
3.) 4 + 4y - 2y = 14
4.) 4y - 2y = 14 - 4
5.) 2y = 10
6.) 2y/2 = 10/2
7.) y = 5
x - y = 2
8.) x - 5 = 2
9.) x = 2 + 5
10.) x = 7
Therefore, x = 7 and y = 5
Step-by-step explanation:
1. First make one of the variables in any equation the subject of the formula
2. Then substitute the variables equating to the subject of the formula
3. Group the like terms,then solve the equation.
4. Replace the value you will find in the first equation into the other equation.
5. Repeat with the same
1) Rational numbers are the numbers which can be expressed as the fraction.
In mathematical form, you can say: anything like: p/q (where, q≠ 0)
2) An Irrational number is the number which can't be expressed in the form of fraction, it repeats upto infinite digits.
Hope this helps!
