Question

Use substitution to solve the system of the equation

Y=-x+4
Y=3x

Answer 1

(1,3)

Explanation:

Substitute 3x for y:

3x=-x+4

Simplify:

3x=4-x

4x=4

x=1

Now, put x back into the equation

y=3(1)

y=3

Check:

3=-1+4

3=4-1

3=3

So the coordinates are (1,3)

Answer 2

x = 1


if you are simply supposed to substitute 3x for Y and solve for x that is your answer. please let me know if that’s what you’re asking and if it is correct. have a lovely day babe :)
