Question

Solve by substitution method --: 18-3y/4 = 11+y using a photo...Useless answers will be reported...Who does it correctly will be marked as the brainliest... Remember, use the substitution method and not the elimination method...​

Answer 1

Answer:

This might be your answer.

Answer 2

$18 - \frac{3y}{4} = 11 + y \\ \\ \frac{72 - 3y}{4} = 11 + y \\ \\ 72 - 3y = 44 + 4y \\ \\ 7y = 28 \\ \\ y = 4$

The substitution method is most useful for systems of 2 equations in 2 unknowns.

We solve one of the equations for one of the unknowns, and then substitute the result into the other equation.

Here, only one unknown variable and one Equation is given.
