Answer: 2/6 or 1/3
Step-by-step explanation:
<span>3x + 2y = 7
y = –3x + 11
replace </span>y = –3x + 11 into 3x + 2y = 7
3x + 2y = 7
3x + 2(–3x + 11) = 7
3x -6x + 22 = 7
-3x = 7 - 22
-3x = -15
x = 5
<span>y = –3x + 11
y = -3(5) + 11
y = -15 + 11
y = -4
x = 5 and y = -4
answer: </span><span>D. (5, –4)</span>

Answer:
8
Step-by-step explanation:
Apparently, you want to evaluate ...
0.1m +8 -12n
for m = 30 and n = 1/4.
Put the numbers where the corresponding variables are and do the arithmetic.
= 0.1×30 +8 -12×(1/4) = 3 + 8 -3
= 8
Answer:
C) No solution
Step-by-step explanation:
Because we know that y=3x-2, we can substitute the value of y into the first equation to get x:
-6x+2y=-6
-6x+2(3x-2)=-6
-6x+6x-4=-6
-4=-6
However, there is one problem! Since both sides are not equal to each other, there's no solution. Therefore, C is the only correct answer.
