Solve the equations by substitution method: A. 2x-y-3=0 and 3x+4y=65.​
PSYCHO15rus [73]

Step-by-step explanation:

\sf 2x-y-3=0\dots \dots (1)

\sf 3x+4y=65 \\ \implies\sf 3x+4y-65=0 \dots\dots(2)

  • from eq (1)

{:}\longrightarrow\sf 2x-y-3=0

{:}\longrightarrow\sf 2x-3=y

{:}\longrightarrow\sf y=2x-3 \dots\dots(3)

  • Substitute the value in eq(2)

{:}\longrightarrow\sf 3x+4y-65=0

{:}\longrightarrow\sf 3x +4 (2x-3)-65=0

{:}\longrightarrow\sf 3x+8x-12-65=0

{:}\longrightarrow\sf 11x-77=0

{:}\longrightarrow\sf 11x=77

{:}\longrightarrow\sf x={\dfrac {77}{11}}

{:}\longrightarrow\sf x=7

  • Substitute the value in eq (3)

{:}\longrightarrow\sf y=2x-3

{:}\longrightarrow\sf y=2 (7)-3

{:}\longrightarrow\sf y=14-3

{:}\longrightarrow\sf y=11

\therefore{\underline{\boxed{\bf (x,y)=(7,11)}}}
