When we solve the equation, we will get the real answer <u>x=40</u> as a variable.
<h3>First Degree Equation</h3>
First degree equation is a mathematical sentence, which has values represented by letters.
These letters can indicate a variable or an unknown - which at the end of the equation will be the final value.
— To solve this equation, just: apply the distributive property (multiply the terms that are outside the parentheses, for the terms that are inside the symbol).
— Next, let's add the real numbers together. Next, we'll subtract the like terms before the equality, thus moving the common term after the equality by adding.
— Finally, let's divide the equation, thus obtaining the final result.
4 + 3(x + 22) = 5x - 10
4 + 3x + 66 = 5x - 10
70 + 3x = 5x - 10
3x - 5x = -10 - 70
-2x = -80
x = 80 ÷ 2
<u>x = 40</u>
Therefore, the correct value of X in this equation, will be <u>x = 40</u>.
<span>Equation at the end of step 1 :</span> (8x + 2 • (x - 7)) - (10x - 14) = 0
<span>Step 2 :</span>Pulling out like terms :
<span> 2.1 </span> Pull out 10x-14
After pulling out, we are left with :
(10x-14) • ( 1 +( (-1) ))
<span>Step 3 :</span>Pulling out like terms :
<span> 3.1 </span> Pull out like factors :
10x - 14 = 2 • (5x - 7)
<span>Equation at the end of step 3 :</span> 0 = 0
-18 + x = 11
