Answer:
5, 17
Step-by-step explanation:
For this problem, you need to create a system of equations.
We can name one number x and the other y.
First equation: 2x + 7 = y
Second equation: x + y - 10 = 12, or x + y = 22.
We know y = 2x + 7, so we can substitute that into the second equation.
x + 2x + 7 = 22.
3x = 15
x = 5.
Plug x back into the first equation:
2 · 5 + 7 = y.
y = 10 + 7
y = 17.
let the unknown answer be equal to f
.-2.1 - f = -3/2
-f = -3/2 + 2.1
-f = 0.6
f = -0.6
