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
