Answer:
x = 10
Step-by-step explanation:

Step 1 : Collect like terms and simplify

Step 2 : Divide both sides of the equation by 2

Step 3 : Simplify by cross cancellation of common term : 2

X = 9
Move the 1 over to make it 3x = 28. The. 28/3 equals 9
The 3rd one
This is because in the graph it’s looking for numbers 70-79 but only with 2 numbers and the 3rd is the only one that fits in the description.
