Could you work out these simultaneous equations 2a plus 3b equals 13 and a plus 2b equals 8 and show me the working out please because I'm really stuck?

I think you have
2a + 3b = 13
2b = 8
If so, the second equation gives, by dividing both sides by 2,
b = 4
then plug in b = 4 in first equation
2a + 3(4) = 13
2a + 12 = 13
2a = 1
a = 1/2

What is the system of equations set in order pairs 3x plus 4y equals 38 5x - 5y equals -30?
Simultaneous equations.
9x-3y equals 24 y equals 3x-8 the system?
The system is simultaneous linear equations
What is the simultaneous equation for 2x plus 5y equals 20?
Another straight line equation is needed such that both simultaneous equations will intersect at one point.
What is y equals 2x-1 and y equals 2x plus 1?
They are two equations in two unknown variables (x and y), which are inconsistent. That is to say, there is no simultaneous solution. An alternative approach is to say that they are the equations of two lines in the Cartesian plane. The lines are parallel and so they do not meet indicating that there is no simultaneous solution.
What are the solutions to the simultaneous equations of x -2y equals 1 and 3xy -y squared equals 8?
They are: (3, 1) and (-11/5, -8/5)
Simultaneous equation 2x-2y equals 10?
Simultaneous suggests at least two equations.

What type of system is 3x plus 2y equals 7 and -4x-3y equals 10?
They are simultaneous equations and their solutions are x = 41 and y = -58
What are the solutions to the simultaneous equations of x -2y equals 1 and 3xy -y squared equals 8?
They are: (3, 1) and (-11/5, -8/5)
What is a word problem using y equals 3x-2 and x-y equals 4 as the system of equations?
It is a simultaneous equation and its solution is x = -1 and y = -5
What is the system of equations and enter the solution as an ordered pair 4x 7y equals 47 5x-4y equals -5?
Do you mean: 4x+7y = 47 and 5x-4y = -5 Then the solutions to the simultaneous equations are: x = 3 and y = 5
What is y equals 2x plus 1 and y equals 2x-3?
A pair of simultaneous equations in two unknowns which are inconsistent - in the sense that there is no solution that simultaneously satisfies both equations. Graphically, the equations are those of two parallel lines (slope = 2). Since, by definition, they cannot meet there is no solution to the system.
What are the solutions to the simultaneous equations of 2s plus 3x equals 31 and 3s plus 4x equals 44?
Through a process of elimination and substitution the solutions are s = 8 and x = 5
