How to solve 4x + 5 = 30? Get the answer and stepwise instruction to solve linear equation in one variable 𝒙.
We have 4x + 5 = 30
First, we move the non x terms to the RHS of the equation. To do this, we subtract 5 from both sides.
Note: if a = b, then a - c = b - cTherefore, 4x + 5 - 5 = 30 - 5
or, 4x = 25
Next, divide both sides by 4, which is the coefficent of x
Note: if a = b, then a ÷ c = b ÷ c4x4 = 254
x = 254 or, x = 6.25
