Answer:
x = -3 and x = -7
Step-by-step explanation:
7 + 2(x+5) = 11
7 + 2x + 10 = 11
2x + 17 = 11
2x = -6
x = -3
7 + -2(x+5) = 11
7 + (-2x) + (-10) = 11
-3 -2x = 11
-2x = 14
x = -7
The numbers are 17 and 39
We can use a system of equation to solve this
x=2y+5
x+y=56
Solving...
2y+5+y=56
3y=51
y=17
x=2(17)+5
x=39
4(x÷9)=2
4 is multiplied to the (x÷9) to get your answer of 2
