Answer & Step-by-step explanation:
On the left:
There are 4 triangles that indicate -x, so this is -4
There are 3 circles that indicate -1, so these are -3.
Insert as an expression:
[tex]-4x-3[/tex]
On the right:
There are 2 triangles that indicate -x, so this is -2x.
There are 2 circles that indicate -1, so these are -2.
Insert as an expression:
[tex]-2x-2[/tex]
Combine both expressions into an equation:
[tex]-4x-3=-2x-2[/tex]
Solve for x. Add 3 to both sides:
[tex]-4x-3+3=-2x-2+3\\\\-4x=-2x+1[/tex]
Add 2x to both sides:
[tex]-4x+2x=-2x+2x+1\\\\-2x=1[/tex]
Isolate the variable. Divide both sides by -2:
[tex]\frac{-2x}{-2} =\frac{1}{-2}\\\\ x=-\frac{1}{2}[/tex]
:Done
