Answer:
Your answer: 87
Step-by-step explanation:
Since you are given what both variables are in the equation, this problem requires you to plug it in.
12(6)+3(5)= ?
You can either do this in a calculator, or do this one step at a time.
12(6)=72
3(5)=15
72+15=87
First you need to set up your equation.
If you read the question it states one equation IS THE SAME AMOUNT of another equation so here it is:
3x+7= 2x+18
You want to find out x in both equations so I’ll help step by step
1. Subtract 2x from both sides
This leaves you with x+7=18
2. Then subtract 7 on both sides
This leaves you with x=11
So x equals 11 for equations.
You can check by plugging in 11 in x. If you get 40 on both sides....
CONGRATS!! You did it
I hope this helped. Have a great day!
