Eq 1: 3x + y = 10
Eq 2: 3x - 2y = -5
Subtract 1 from 2: -3y = -15
Divide by -3: y = 5
Substitute y = 5 in Eq 1: 3x + 5 = 10 so x = 5/3
Confirm in Eq 2: 3 x 5/3 - 10 = 15/3 - 10 = 5 - 10 = -5.
QED
Another straight line equation is needed such that both simultaneous equations will intersect at one point.
Solving tne simultaneous equation gives x = 19.8 and y = -2.2
x+4y = 7 x+y = 4 Subtract the second equation from the first equation: 3y = 3 Divide both sides by 3 in order to find the value of y: y = 1 Substitute the value of y into both original equations in order to find the value of x: Therefore it follows that: x = 3 and y = 1
It's a simultaneous equation and can be solved by elimination which works out as:- x = -4 and y = 1
It is a simultaneous equation and when solved its solutions are x = 71/26 and y = 50/13
Simultaneous suggests at least two equations.
Another straight line equation is needed such that both simultaneous equations will intersect at one point.
It seems to be some kind of simultaneous equation with too many equality signs in it.

x = -1/5 and y = 14/5 Solved by forming a simultaneous equation and eliminating y.
This equation is not possible unless you are given another equation related to x and y. Then you could use simultaneous equations to solve this. However in this came this question is impossible
That equation cannot be solved since there are 2 unknown in the equation (x and y) but only 1 equation. The number of unknowns must be equal to the number of equations (for simultaneous equations)
Plot the straight line representing 2y = 12 - x. Plot the straight line representing 3y = x - 2 The coordinates of the point of intersection of these two lines is the solution to the simultaneous equations.
