for this simultaneous equations:
x + 2y = 1,
-x + 5y = 12.
would the two solutions be
x = -3 and y = 2
sorry i mean -x + 5y = 13
i really need help with my math homework
excuse me..does that have anything 2 do wiv my queation??
unless ur dng the same course as me
yes, your solutions are correct.
Yes, those are the solutions.
To solve the given system of simultaneous equations, you can use the method of substitution or the method of elimination. Let's solve it using the method of substitution:
Given equations:
1) x + 2y = 1
2) -x + 5y = 13
Step 1: Solve equation 1 for x in terms of y:
x = 1 - 2y
Step 2: Substitute the value of x from equation 1 into equation 2:
-(1 - 2y) + 5y = 13
-1 + 2y + 5y = 13
7y - 1 = 13
Step 3: Simplify the equation:
7y = 14
y = 2
Step 4: Substitute the value of y into equation 1 to find x:
x + 2(2) = 1
x + 4 = 1
x = -3
Therefore, the solution to the given system of equations is x = -3 and y = 2.
