Hello!
To solve this equation, we need to isolate the variable on one side of the equation to see what it equals.
As you can see, 2.7 is added. To get it onto the other side and cancel it from the one side, you will subtract it from both sides as shown below. Note that because of the commutative property, we can switch the places of 2.7 and x.
x+2.7-2.7=17-2.7 (Note that 2.7=2.7 is 0 in this equation.
x=14.3
Our solution is x=14.3
I hope this helped you learn how to solve equations a bit better!
Answer:
r = -4
Step-by-step explanation:
Step 1: Write out equation
4r + 8 + 5 = -15 - 3r
Step 2: Combine like terms
4r + 13 = -15 - 3r
Step 3: Add 3r to both sides
7r + 13 = -15
Step 4: Subtract 13 on both sides
7r = -28
Step 5: Divide both sides by 7
r = -4
