Answer:
x= -1/2 and -32
y = -10
Step-by-step explanation:
1) 2(-4x-8y)= (-48)2
8x+3y =-34
*to create a way to cancel out the x*
2) -8x-16y= -96
8x+3y= -34
*add them
-8x +8x =0
-16y + 3y = -13y
-96+ -34= -130
3) -13y =-130
isolate y
4) y = -10
*plug in* to find x into both original equations*
5) 8x + 3(-10) = -34. -4x-8(-10)= -48
*follow order of operations to solve for x
6) 8x -30 =-34. -4x +80 = -48
7) 8x =-4. -4x =128
8) x= -1/2. x = -32
Answer:
The answer is b= 7/2
Step-by-step explanation:
hope this helps
A(b-c)=d
Ab-Ac=d
-Ab -Ab from both sides
-Ac=d-Ab
divide -A
c=d-Ab over -A and the -A's should cancel so it should be c=db <span />
