Answer:

Step-by-step explanation:

Each triangle = - x

There are 4 of them

They equal -4x

The circles all = 1

There are 3 circles on the left

They equal 3*1 = 3

There are eleven circles on the right.

-4x + 3 = 11             Subtract 3

-4x/-4 = 8               Divide by - 4

x = 8/-4

x = -2
