Answer: 6; 5
Explanation:
Based on the questions, we set up two equations, let the x be the first number, and y be the second number.
x + y = 11
2x - y= 7
x = 11 - y [Subtract y from both side]
2x - y = 7
2(11 - y) - y = 7 [Plug in 11-y for x, solve for y]
22 - 2y - y = 7
22 - 3y = 7
-3y = -15 [Subtract 22 from both side]
y = 5
x + y = 11 [Plug in 5 for y, solve for x]
x + 5 = 11 [Subtract 5 from both side]
x = 6
