Hey there! :)
-2x - 1 - 2x + 43 = 97 + 7x
Add like terms!!
(-2x - 2x) + (-1 + 43) = 97 + 7x
Simplify.
-4x + 42 = 97 + 7x
Now, we have to isolate x. To do this, we must subtract 42 from both sides.
-4x = 97 + 7x - 42
Then, subtract 7x from both sides.
-4x - 7x = 97 - 42
Simplify.
-11x = 55
Divide both sides by -11.
x = -5
~Hope I helped!~
