Answer: x=35
Step-by-step explanation:
4x-80=60
+80 +80 (add 80 to both sides)
4x = 140
4x/4 140/4 (divide by 4 on both sides)
x=35
Answer:
Hi there!
Here's a play-by-play of how to solve this!
4x-80=60
The goal is to get the x on one side and the whole numbers on the other!
To get rid of the -80 on the left side, we must find the additive inverse, or what number when added to it equals 0. -80 plus 80 = 0, so we add 80 . What we do to the left side MUST be done to the right as well!!
4x-80= 60
+80. +80
4x +0 = 140
4x=140
X cannot have a coefficient when solved for. We must divide out the coefficient, in this case 4. What we do to the left side must be done to the right!
4x= 140
/4. /4
x= 140/4
x= 35
Here are the steps! Hope this helps! Let me know if you need clarification!
