Answer: 4x-20=58
+20 +20
4x=78
/4 /4
x=19.5
Step-by-step explanation: Parenthesis first. Multiply 4 times x (which is 4x) and 5 times 4 (which is 20). So you get 4x-20-2=56. Move the (-2) over to the other side using inverse operations, making it 4x-20=58. Then move over the 20, again using inverse operations, making it 4x=78. Then isolate the variable by dividing both sides by 4 leaving you with x=19.5. You can check the work by plugging it in:
4(19.5-20)-2=56
78 - 20 = 58 (moved the -2 over to the other side)
58 = 58. That is true so the answer is correct.
