The system of equation A can be modified as system B, and the modified equations are -x - 2y = 7 and-16y = 32 solutions to the system of equation is (-3,-2) option (D) is correct.
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have two linear equations:
System A
-x - 2y = 7
5x - 6y = -3
From equation A:
x = -2y - 7
Plug this value in the equation second.
5(-2y - 7) - 6y = -3
-10y - 35 - 6y = -3
-16y = -3 + 35
-16y = 32
System B
-x - 2y = 7
-16y = 32
y = - 2
x = -3
Solutions:(-3,-2)
Thus, the system of equation A can be modified as system B, and the modified equations are -x - 2y = 7 and-16y = 32 solutions to the system of equation is (-3,-2) option (D) is correct.
