Solve -3x + 10 = 7

How to solve -3x + 10 = 7? Get the answer and stepwise instruction to solve linear equation in one one variable 𝒙.

Steps for finding the solution

We have -3x + 10 = 7

First, we move the non x terms to the RHS of the equation. To do this, we subtract 10 from both sides.

Note: if a = b, then a - c = b - c

Therefore, -3x + 10 - 10 = 7 - 10

or, -3x = -3

Next, divide both sides by -3, which is the coefficent of x

Note: if a = b, then a ÷ c = b ÷ c

-3x/-3 = -3/-3

x = -3/-3

To simplify, divide both numerator and denominator by 3, which is the GCF of 3 and 3:

x = -1/-1 or, x = 1
