If this is just an expression, then all you have to do is combine like terms, or groups of numbers and variables that have the same variable.
When simplified, you get the equation
-12+ 16r or
-18+6+3r+13r=16r-12

Solution
2.5(10 - x) + 10 = 72 - 1.5x*(5x + 12) The first step is to remove the brackets. Be very careful you understand the bracket on the right.
25 - 2.5x + 10 = 72 - 7.5x - 18 Study the signs carefully. Collect like terms.
35 - 2.5x = 54 - 7.5x Add 7.5x to both sides.
35 - 2.5x + 7.5x = 54 - 7.5x + 7.5x
35 + 5x = 54 Subtract 35 from both sides.
5x = 19 Divide by 5
x = 19/5
x = 3 4/5 = 3.8
Check
When you numbers are so cumbersome, you should check the answer.
<em><u>LHS</u></em>
2.5(10 - 3.8) + 10
2.5(6.2) + 10
15.5 + 10
25.5
<em><u>RHS</u></em>
72 - 1.5(5*3.8 +12)
72 - 1.5(19 + 12)
72 - 1.5(31)
72 - 46.5
25.5
<em><u>RHS = LHS</u></em> The solution checks.
Answer:
f(-5) = 6
Step-by-step explanation:
f(x) = x + 11
Let x = -5
f(-5) = -5+11
f(-5) = 6
