Answer:
X = 32
<u>Step-by-step explanation:</u>
Step 0, Set up the equation like this:
3(30 + x) = 154 + x
Step 1, Expand 3(30 + x)
=> 90 + 3x = 154 + x
Step 2, Subtract both side by 90
=> 3x = 64 + x
Step 3, Continue subtract both side by x
=> 2x = 64
Step 4, Divide both side by 2
=> x = 32
11 9/8
Or
Simplified 12 1/8
Make denominators the same
And then add
