Answer:
If you use the addition property of equality, what number would you add to both sides of the equal sign to isolate the variable?
You would subtract 5/7 from both sides of the equation
What is the solution?
x = 26/7 or 3 and 5/7
Step-by-step explanation:
x + 5/7 = 31/7
Subtract 5/7 from both sides of the equation:
x + 5/7 - 5/7 = 31/7 - 5/7
x = 26/7
Answer:
The value of is 17-18x and is -7-18x.
Step-by-step explanation:
It is given in the question functions f(x) as 3x+2 and g(x)=5-6x.
It is required to find and .
To find , substitute g(x) for x in f(x) and simplify the expression.
To find , substitute f(x) for x in g(x) and simplify the expression.
Step 1 of 2
Substitute g(x) for x in f(x) and simplify the expression.
Step 2 of 2
Substitute f(x) for x in g(x) and simplify the expression.

Answer:</h2>
<u>The expression is</u><u> 5(40+80)</u>
<h2>
Step-by-step explanation:</h2>
The sum of 40 and 80 can be written as
(40+80)
and when we take the 5 times of the sum
we can write as
5(40+80)
3(a-b) and 3a-3b. Equivalent
2a(2+b) and 4ab. Not equivalent
