Question

3x-2y=5
-6x+4y=7
Solve the linear equation algebraically!

Answer 1

can anyone answer please?

Answer 2

try using substitution or elimination

Answer 3

i know that. i dont understand HOW to use it though.

Answer 4

okay take one of the equations, anyone and make it equal x or y ur choice.
for ex: 3x-2y=5
+2y =2y
3x=5+2y
/3 /3
x=5/3+2/3y
Now take the other equation and subsitute the x in that equation for 5/3+2/3y and solve.

Answer 5

3x-2y=5..................(1)
-6x+4y=7............(2)
y=(-5+3x)/2 [ from equation 1]
sub y in (2)
-6x+4[(-5+3x)/2=7
0=17this means x is contained in empty set
hence the system of linear equations is inconsistence(no solution)
