Answer 1

Resposta:

Explicação passo a passo:

Solution :-

Rearrange unknown terms to the left side of the equation: $\left \{ {{15x+11x=-39+13} \atop {7y-5y=15-11}} \right.$

Combine like terms: $\left \{ {26x=-39=13} \atop {2y=15-11}} \right.$

Calculate the sum or difference : $\left \{ {{26x=-26} \atop {2y=4}} \right.$

Divide both sides of the equation by the coefficient of variable : $\left \{ {{x=-26 / 26} \atop {2y=4}} \right.$

Reduce as fraction: $\left \{ {x=-1} \atop {2y=4}} \right.$

Reduce the greatest common factor on both sides of the equation: $\left \{ {{x=-1} \atop {y=2}} \right.$

Answer : $\left \{ {{x=-1} \atop {y=2}} \right.$
