Answer :
The value of x is 2 and y is -1/2
equations are 3x-2y=7 --1
7x+2y=13 --2
lets consider 3x-2y=7 as equation 1,
consider 7x+2y=13 as equation 2
by putting both the equations :-
3x-2y=7
7x+2y=13
we get 10x=20
x=20/10
x=2
Now by putting the value of x in equation 1;
3(2)-2y=7
6-2y=7
-2y=1
y=-1/2
What is a simultaneous equation?
Simultaneous equations are two or more algebraic equations that share variables e.g. x and y. They are called simultaneous equations because the equations are solved at the same time. Each of these equations on its own could have infinite possible solutions.
What is meant by algebraic equation?
algebraic equation, a statement of the equality of two expressions formulated by applying to a set of variables the algebraic operations, namely, addition, subtraction, multiplication, division, raising to a power, and extraction of a root.
