The solution of bivariate linear equation 2x + 3Y = 15 is () A. One B. two C. three D. four
If x = 0 is substituted into the equation, y = 5; if x = 3 is substituted into the equation, y = 3; if x = 6 is substituted into the equation, y = 1, then there are three solutions of the binary linear equation in the range of natural numbers. Therefore, C is selected
The group number of natural number solutions of binary linear equation x + 3Y = 9 is
y=0,x=9
y=1,x=6
y=2,x=3
y=3,x=0
We can consider x = 9-3y ≥ 0
0≤y≤3
There are four groups
[questions are welcome]
Xiao Ming and Xiao Wen solve a system of linear equations of two variables {cx-3y = - 2 ax + by = 2, Xiao Ming correctly solves x = 1 y = - 1, and Xiao Wen wrongly copies the solution of C to get x = 2 y = - 6
cx-3y=-2;
If Xiaowen is only over wrong C, the solution is that Xiaowen copies C to - 10
Xiao Ming got a positive solution c = - 5
Bring Xiaoming and Xiaowen's solution into you
a-b=-2;
2a-6b=2;
The results show that a = 5 / 2; b = 1 / 2;
So a + B + C = - 2
