2x -3y = 12;
x + 3y = 6;
__________(+)
3x = 18;
x = 18÷3;
x = 6;
Then, 3y = 6 - 6;
3y = 0;
y = 0÷3;
y = 0;
The answer is B, congruent
Answer:
c is the correct answer
Step-by-step explanation:
<span>2(a+b)=c
2a + 2b = c
2b = c - 2a
b = (c - 2a)/a
answer
</span><span>D. b = (c−2a)/2 ; distribute 2 to get 2a+2b, subtract 2a, then divide by 2.</span>
