What is the solution (a, b) to this system of linear equations? 3a 6b=45 2a-2b=-12 (-27, 6) (-1, 7) (1, 7) (27, -6)
1 answer:
The solution of the system of linear equation are (1, 7)
<h3>How to solve system of equation?</h3>
3a + 6b = 45
2a - 2b = -12
multiply equation(ii) by 3
Therefore,
3a + 6b = 45
6a - 6b = -36
9a = 9
a = 1
Hence,
2(1) - 2b = -12
2 - 2b = -12
-2b = -12 - 2
- 2b = - 14
b = -14 / -2
b = 7

Step-by-step explanation:
Answer:
width = 12 yards
Step-by-step explanation:
width: x
length: x + 3
perimeter: 54
x + x + (x + 3) + (x + 3) = 54
4x + 6 = 54
subtract 6 from both sides
4x = 48
x = 12
width: 12
length: 12 + 3 = 15
