Answer:
look at the picture for the answer
What is the system? (Is there supposed to be an image?)
x - 2y = 5
-3x + 2y = 7
-----------------add
-2x = 12
x = 12/-2
x = -6
-3x + 2y = 7
-3(-6) + 2y = 7
18 + 2y = 7
2y = 7 - 18
2y = - 11
y = -11/2
solution is : (-6,-11/2)...x = -6 and y = -11/2
Answer:
(-1,2)
Step-by-step explanation:
1. substitute y=2x+4 in for y
2. solve 2x+4=5x+7 and you get x=-1
3. sub in -1 for x and solve
4. y=2
5. solution is (-1,2)
By this equation: d = 4(32), we know what d equals, which means we have the value of d.
d= 4*32
d = 128
