Subtract the two equations: 2x3y(2x+8y)=411

Remove parentheses: 2x3y2x8y=411

Cancel one variable: 3y8y=411

Combine like terms: 11y=411

Calculate the sum or difference: 11y=7

Divide both sides of the equation by the coefficient of variable: y=711

Rewrite the fraction: y=711

Substitute into one of the equations: 2x3×711=4

Multiply both sides of the equation by the common denominator: 2x×113×7×1111=4×11

Reduce the fractions: 2x×113×7=4×11
Multiply the monomials: 22x3×7=4×11
Calculate the product or quotient: 22x21=44
Rearrange unknown terms to the left side of the equation: 22x=44+21
Calculate the sum or difference: 22x=65
Divide both sides of the equation by the coefficient of variable: x=6522
The solution of the system is:x=6522y=711
Answer: x=6522y=711
