Answer:
x = -3, y = -4
(-3, -4)
Step-by-step explanation:
solve each equation for y (the first equation is already solved for y, so just do the second equation)
-x -y =7
<u>+x +x</u>
-y = x + 7 eliminate the negative by switching all signs
y = -x - 7
now that both equations equal y, you can set them equal to each other:
-x - 7 = 3x + 5
solve for x
-x - 7 = 3x + 5 move the variable to one side of the equation
<u>+x +x </u>
-7 = 4x + 5 move the constant to the other side of the equation
<u>-5 -5</u>
-12 = 4x single out x by dividing the whole thing by 4
<u>÷4 ÷4</u>
-3 = x
now substitute -3 for x in one of the original equations (it doesn't matter which equation)
y = 3(-3) +5 solve
y = -9 +5
y = -4
have a wonderful day! :)
Answer:
what?
Step-by-step explanation:
Answer:
54°
Step-by-step explanation:
If GJ is an angle bisector that the 2 angles are congruent so their measures are equal
7x -9 = 2x +36
7x -2x = 36 +9
5x = 45
x= 45/5 = 9
measure of angle FGH = 7x-9 = 7*9 -9 = 54°
Answer:
Step-by-step explanation:
Which system of equations is equivalent to this system?
6x + 4y = 126x + 4y = 12
3x + y = 8 3x + y = 8
−4x + 4y = 48-4x + 4y = 48
3x + y = 8 3x + y =8
4x + 4y = 484x + 4y = 48
3x + y = 8 3x + y = 8
<h2>2x + 4y = 122x + 4y = 12</h2><h2> 3x + y = 8</h2>
