X= -7
2+x=-5 if you move the constant to the right side it would be x=-5-2 which equals -7
A= 5 + 2 = 7
You get this by doing the inverse operation so minus 2 by 2 and 7 then you get your answer so it should look like this
X+2= 7
-2. -2
———
X= 5
B: 15-4=11
+4. +4
————-
X= 15
C: 4(3) = 12
D: 50/5 = 10
Btw this should be easy, try doing it on to your own now.
Answer:
x= 4, y= -1
Step-by-step explanation:
3x -5y= 17 -----(1)
y= x -5 -----(2)
Substitute (2) into (1):
3x -5(x -5)= 17
Expand:
3x -5x +25= 17
-2x= 17 -25
-2x= -8
x= -8 ÷(-2)
x= 4
Substitute x= 4 into (2):
y= 4 -5
y= -1
Answer: 3>x
Step-by-step explanation:
2 > x - 1
+1 +1
3 > x
