Presumably this is a simultaneous equation question which can be solved using the elimination method?
4(x+2y = -1)
4x+3y = -9
First multiply all terms in the top equation by 4:
4x+8y = -4
4x+3y = -9
Subtract the bottom equation from the top equation in order to eliminate x remembering that a - - is equal to a + So -4 - -9 is equal to 5:
5y = 5 => y = 1
Substitute the value of y into the original equations to find the value of x:
Therefore: x = -3 and y = 1

How do you solve 3x plus 2y equals 4 4x plus 3y equals 7?
You need to organise your question properly. 3x+2y=4 4x + 3y= 7? Is 4 4x = 44x or 4-4x or 4+4x How can there be 2 equal signs in 1 equation?
Answer for 3y2-2y plus 6xy-4x?
3y2 - 2y + 6xy - 4x = y(3y - 2) + 2x(3y - 2) = (y + 2x)*(3y - 2)
Is 3x plus 2y equals 7 and -4x-3y equals 10 dependent?
Yes and their solutions are x = 41 and y = -58
What is 2x-3x plus 4x plus 3y-2y?
3x + y
What is 3y equals 4x plus 9 in standard form?
-4x + 3y = 9
