2\5 + 2\4
Lcm of 4 and 5 is 20
So 20 divided by 5 is 4 × 2 = 8 and 20 divided by 4 is 5 × 2 = 10
10+ 8 =18\20 = 9\10
X= 2 is the axis of symmetry

Answer:
x = -4
Step-by-step explanation:
I'm assuming we solve for x, so Let's solve for x!

Now subtract -12 from each side.
4x = -16
Now, divide by 4 from each side.
x = -4
