x=8+3y2x-5y=8

Short Answer

Expert verified

The solution of given system of equations is x=16, y=8.

Step by step solution

01

Step 1. Substitute value of one variable from one equation to another.

Substitute8+3y for x into2x5y=8 and simplify.

28+3y5y=816+6y5y=816+y=8

02

Step 2. Solve for one variable.

Subtract 16 from both the sides of the equation obtained in step 1 to find the value of y.

16+y16=816y=8

03

Step 3. Solve for another variable.

Substitute –8 for y into x=8+3y, to find the value of x.

x=8+3×8=824=16

Therefore, the solution of given system of equations is x=16, y=8.
