Answer:
x = -6, y = -2
Step-by-step explanation:
2x-7y = 2
3x + y = -20
We need to cancel out either x or y to solve the equation. I'll cancel out x first
3(2x-7y = 2)
-2(3x+y=-20)
___________
6x-21y = 6
-6x -2y = 40
____________
-23y = 46
y = -2
Plug the value for y in one of the 2 equations to solve for x
2x -7(-2) = 2
2x+14=2
2x = -12
x=-6
Answer:
the answer to the questions are c,b,a
<span>6x=-16
Divide 6 on both sides
Final Answer: x=-16/6 or -2 4/6 or -2 2/3 *All answers are equivalent to each other.</span>
Answer:
$927.113
Step-by-step explanation:
50-7=43
43×18.94=814.42
100-15=85
100%=18.94
what about 85%
85×18.94=1609.9÷100=16.099
16.099×7=112.693
814.42+112.693= 927.113
The equation should be b^2-c^2 = your answer
