10x + 41y142x + 2y
10x + 41y - 142x + 2y = 10x - 142x + 41y + 2y = (10 -142)x + (41 + 2)y = -132x + 43y
10x + 2y + 8z - 5x + 4z - 4y = 10x - 5x + 2y - 4y + 8z + 4z = (10 - 5)x + (2 - 4)y + (8 + 4)z = 5x - 2y + 12z
To solve this, you would normally set up a systems of equations 10x + 2y = 10 10x + 2y = 11 However, it clearly makes no sense and has no answer. To prove this mathematically, subtact the two equations. 10x - 10x = 0 2y - 2y = 0 10-11 = -1 Therefore, it is basically saying that 0 + 0 = -1 Obviously, that is incorrect, so this question has no solutions.

10x - 5y + 2x - 3y = 12x - 8y

3x - 2y + 7x + 4y = 3x + 7x - 2y +4y = (3+7)x + (-2+4)y = 10x + 2y

2x + 2y = 14 eqn 12x - y = 5 eqn 2Solve for X and Y.Simplify eqn 2 to solve for y2x - y = 5subtract sx from both sides-y = 5 - 2xmultiple both sides by -1y = 2x - 5substitute 2x - 5 into eqn 1 for y2x + 2y = 142x + 2(2x -5) = 142x + 4x - 10 = 146x - 10 = 14add 10 to both sides6x = 24divide both sides by 10x= 4Substitute x = 4 into eqn 2y = 2(4) - 5y = 8 - 5y = 3X = 4 and y = 3
10x-2y=30
To simplify the expression 13x + 2y - 10x - 7y, you first combine like terms. Group the x terms together and the y terms together: (13x - 10x) + (2y - 7y). This simplifies to 3x - 5y. Therefore, the simplified expression is 3x - 5y.
