Hi there! :)
<u><em>Answer:</em></u>
<u><em>=28b-57</em></u>
<u><em>*The answer must have a positive sign.*</em></u>
Step-by-step explanation:
<h2><u>Lesson: Distributive property</u></h2>
Distributive property: a(b+c)=ab+ac
First, you expand or multiply by the numbers from left to right.
It change positive to negative sign.
Finally, you add/subtract by the numbers from left to right.
It change positive to negative sign.
<em><u>Final answer is 28b-57</u></em>
I hope this helps you!
Have a nice day! :)

Answer: A (the first one)
Step-by-step explanation:
Rewrite as = 3x+4 and solve:
Answer:
In mathematics, to solve an equation is to find its solutions, which are the values (numbers, functions, sets, etc.) that fulfill the condition stated by the equation, consisting generally of two expressions related by an equals sign. When seeking a solution, one or more variables are designated as unknowns.
Answer:
a. x=8
b.Step 1: Simplify both sides of the equation.
2(2x−2)=4x−4
(2)(2x)+(2)(−2)=4x+−4(Distribute)
4x+−4=4x+−4
4x−4=4x−4
Step 2: Subtract 4x from both sides.
4x−4−4x=4x−4−4x
−4=−4
Step 3: Add 4 to both sides.
−4+4=−4+4
0=0
Answer:
All real numbers are solutions.
c. Step 1: Simplify both sides of the equation.
3(x+1)=4x+7−x
(3)(x)+(3)(1)=4x+7+−x(Distribute)
3x+3=4x+7+−x
3x+3=(4x+−x)+(7)(Combine Like Terms)
3x+3=3x+7
3x+3=3x+7
Step 2: Subtract 3x from both sides.
3x+3−3x=3x+7−3x
3=7
Step 3: Subtract 3 from both sides.
3−3=7−3
0=4
