<span>x=1/4y+2</span>
−4x+3y=4-------> substitution method
<span> -4(1/4y+2)+3y=4</span>
-y-8+3y=4-
--------> 2y=4+8- ----->y=6
x=1/4y+2-
-----> ¼(6)+2=7/2
the
answer is (7/2,6)
Elimination
first i would divide the second equation by -2.
x - y = -2
-x- 2y = -19
the x is eliminated.
-3y = -21
divide each side by -3.
y = 7
plug 7 in for y to solve for x
x-7 = -2
x = 5
(5,7)
You substitute the given value of y into the equation
8x+4(3x+8)=12
Solve the equation for x
x= -1
Substitute the given value of x into the equation y=3x+8
y=3x (-1)+8
Solve the equation for y
y=5
Answer: (x= -1) (y= 5)
