Answer:
The answer is A
Step-by-step explanation:
Answer:
yes cause they are the same #s
Step-by-step explanation:
147/8 should be the answer. You had to change the mixed fraction into an improper fraction. Then switching 1/3 into 3/1 and then multiply.
-7x+14y=-14
-3x+7y=-3
when using elimination you need to multiply or divide one equation to be able to “eliminate” a variable.
-7x+14y=-14
-2(-3x+7y=-13)
multiply the second equation by -2
-7x+14y=-14
6x-14y=6
simplify
-1x=-8
divide by -1 on both sides to isolate the x
x=8
now you can plug in 8 for x in one of the equations.
-3(8)+7y=-3
simplify
-24+7y=-3
add -24 to both sides the isolate the constant and variable
7y=21
now divide by 7 on both sides to isolate y
y=3
this system of equation had one solution at (8, 3)
i hope this helps :)
