Question

x=4y 3x-2y=20please, check

Answer 1

Step 1:

Write the two equations

$\begin{gathered} \text{x = 4y} \\ 3x\text{ - 2y = 20} \end{gathered}$

Step 2:

Use substitution method to solve for x and y.

Substitute x = 4y into the second equation

Step 3:

$\begin{gathered} 3x\text{ - 2y = 20} \\ 3(4y)\text{ - 2y = 20} \\ 12y\text{ - 2y = 20} \\ 10y\text{ = 20} \\ \text{y = }\frac{20}{10} \\ y\text{ = 2} \end{gathered}$

Step 4

Solve for x

x = 4y

x = 4(2)

x = 8

Final answer

x = 8 , y = 2
