Let's solve your equation step-by-step.

x=48 simple there as for if we use C

3x+x=48

Step 1: Simplify both sides of the equation.

3x+x=48

(3x+x)=48(Combine Like Terms)

4x=48

4x=48

Step 2: Divide both sides by 4.

4x

4

=

48

4

x=12 and we only get 12 there for the correct answer in lo and behold B

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
