The sum of five times a number and seven is equal to twelve. A) 5n + 7 = 12
B) 5(n + 7) = 12
C) (5n)(7) = 12
D) 5+n + 7 = 12
What’s the answer

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)
