Answer:
14
Step-by-step explanation:
2 (x+4) = 3(x-2)
(distribute)
2*x + 2*4 = 3*x + 3 * -2
2x + 8 = 3x + -6
+6 +6 (add 6 on both sides)
2x + 14 = 3x
-2x -2x (subtract 2x on both sides)
14 = x
x is 14, we have found x.
Answer:
-27/5 and 29
Step-by-step explanation:
First, simplify everything. You get 20x - _ * 5/9 + 9x = 3 + _ * x.
This is 29x - _ * 5/9 = 3 + _ * x.
The 2nd blank must be 29 because there is nothing else to alter it.
Using the same logic, the first blank is -27/5.
adding the 2 equations eliminates x and gives:-
5y = 60
y = 12
Plug y = 12 into the first equation:-
2x + 3(12) = 40
2x = 40 - 36 = 4 so x = 2
Answer is x = 2 and y = 12.
Answer:
x can be all real numbers
Step-by-step explanation:
1 - 5x = -5x + 1
-5x+5x=1-1
0=0
