Question

Solve the system of equations.
3x + 4y = 23
5x + y = 27

Answer 1

lets multiply the bottom equation by -4 to eliminate y when we add the equations:

3x+4y=23
-20x-4y=-108

add them

-17x=-85
x=5
plug back in and y=2

Answer 2

for solving these type of questions try eliminating a variablbe an solve for the other :
multiply the 2nd equation by -4 to eliminate y when we add the equations: 3x+4y=23 -20x-4y=-108 add them -17x=-85 x=5 and so y=2

Answer 3

multiply up by 1 and down by 4
3x+4y=23
20x+4y=108
then you subtract
-17x=-85
x=5
substitute for y

Answer 4

ok, so we all agree haha

Answer 5

:D yea we do :D

Answer 6

So are there 2 answers? y and x?

Answer 7

yes , since u where asked to solve an equation containing 2 unknows x and y, u will finally find 2 answers .

Answer 8

Ohh okay.
