The system of equations shown below is graphed on a coordinate grid:

3y + x = 4
2y − x = 6

Which statement is true about the coordinates of the point that is the solution to the system of equations?

It is (−2, 2) and lies on both lines.
It is (−5, 3) and lies on both lines.
It is (−5, 3) and does not lie on either line.
It is (−2, 2) and does not lie on either line.

Let's solve your system by substitution.

3y+x=4;2y−x=6

Rewrite equations:

x+3y=4;−x+2y=6

Step: Solvex+3y=4for x:

x+3y=4

x+3y+−3y=4+−3y(Add -3y to both sides)

x=−3y+4

Step: Substitute−3y+4forxin−x+2y=6:

−x+2y=6

−(−3y+4)+2y=6

5y−4=6(Simplify both sides of the equation)

5y−4+4=6+4(Add 4 to both sides)

5y=10

5y

5

=

10

5

(Divide both sides by 5)

y=2

Step: Substitute2foryinx=−3y+4:

x=−3y+4

x=(−3)(2)+4

x=−2(Simplify both sides of the equation)

x=−2 and y=2

Your line would also lay on both lines so the answer would be the first one: It is (−2, 2) and lies on both lines.

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2

4+4+2x

or

2x+8
