Step-by-step explanation:
i'm sorry if it is wrong please comment if it is so i can fix it
If the equations are 6x+3y=9 and 5x+4y=10 then to solve the equation we need to multiply the first equation by –4,Multiply the second equation by 3,Add the resulting system of equations and then cancel negative 12y and 12y which is option d.
What is equation?
Equation is like a relationship between two or more variables that are expressed in equal to form. Equation of two variables look like ax+by=c. It may be linear equation, quadratic equation , cubic equation, etc.
How to solve equation?
We have been given two equations :
6x+3y=9-----------1
5x+4y=10----------2
Multiply equation 1 by -4 and equation 2 by 3 and add both equations.
-24x-12y+15x+12y=-36+30
Cancel negative 12y and 12 y.
-9x=-6
x=-6/-9
=2/3
Hence if the equations are 6x+3y=9 and 5x+4y=10 then to solve the equation we need to multiply the first equation by –4,Multiply the second equation by 3,Add the resulting system of equations and then cancel negative 12y and 12y which is option d.
