Solve for x.
7x + 9 = 6x - 5
x= -4
x = -14
X= 4
1 1
+
x = 14

4

Step-by-step explanation:

7x + 9 = 6x -5           (First, get x on one side)

-6x        -6x

x + 9 = -5                    (now, add 9 to both sides to get x by itself)

 +9     +9    

Leaving with,

x = 4

And so, x is equal to 4.      

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)
