Answer:
A) 5x-6y=3
B) 7y=2x+8
B) -2x + 7y = 8 then multiplying "B" by 2.5
B) -5x +17.5y = 20 then adding this to A
A) 5x -6y = 3
11.5y = 23
y = 2
x = 3
Step-by-step explanation:
Answer:
3 less than or equal to x less than or equal to 13
3 ≤ x ≤ 13
Step-by-step explanation:
2^n = 1/8
Try each one of the options in turn
The question marks are negatives right?
10x-7(3x+8)=-26x+4
first you have to isolate the variable
then you divide each side by factores that don't contain the vairable
for this problem if you follow those steps
X=4
-7(3x+8)=-36x+4
-11(3x+8)=-36x+4
