Answer:
1. x = 2
2. x = 3
Step-by-step explanation:
<h2>First question</h2>
4 + 7x = 12 + 3x
Solve for X
Bring X to one side of the equation, pick a side.
In this case I will move the X to the left side
Subtract 4 from both sides to get 7x by itself
7x = 8 + 3x
Now subtract 3x from both sides to move it to the left
4x = 8
Now get x by itself by dividing by 4
x = 2
<h2>Second question</h2>
8x + 6 = 2x + 24
Chose a side to isolate the X
I will chose the left because 24 is large and subtracting from that is easier
Subtract 6 from both sides to isolate 8x
8x = 2x + 18
Subtract 2x to isolate 18 and bring all X's to one side. I chose the left side.
6x = 18
Devide by six from both sides to further isolate x
X = 3
