7 + x = 13 + 4x
To solve the equation 7 + x = 13 + 4x, we need to find the value of x that satisfies the equation
To solve the equation 7 + x = 13 + 4x, we need to find the value of x that satisfies the equation.
First, let’s simplify the equation by combining like terms on both sides. We can do this by subtracting x from both sides and subtracting 13 from both sides:
7 + x – x = 13 + 4x – x
On the left side, x – x cancels out, leaving us with just 7:
7 = 13 + 3x
Now, we can simplify further by subtracting 13 from both sides:
7 – 13 = 13 + 3x – 13
On the left side, 7 – 13 equals -6:
-6 = 3x
To isolate x, divide both sides of the equation by 3:
-6/3 = 3x/3
Simplifying, we have:
-2 = x
Therefore, the solution to the equation is x = -2.
