In order to solve for x, we need to isolate the variable on one side of the equation. We can do this by performing the same operation (adding, subtracting, multiplying, or dividing) to both sides of the equation in order to maintain equality.
Given: 8x - 5 = 3x + 20
Subtract 3x from both sides:
8x - 3x - 5 = 3x - 3x + 20
5x - 5 = 20
Add 5 to both sides:
5x - 5 + 5 = 20 + 5
5x = 25
Divide both sides by 5 to solve for x:
5x/5 = 25/5
x = 5
Therefore, x = 5.
Solve for x: 8x − 5=3x + 20.(1 point)
