15x+20y=8\times 5+3
Multiply both sides of the equation by 5.
15x+20y=40+3
Multiply 8 and 5 to get 40.
15x+20y=43
Add 40 and 3 to get 43.
15x=43-20y
Subtract 20y from both sides.
\frac{15x}{15}=\frac{43-20y}{15}
Divide both sides by 15.
x=\frac{43-20y}{15}
Dividing by 15 undoes the multiplication by 15.
x=-\frac{4y}{3}+\frac{43}{15}
Divide 43-20y by 15.
15x+20y=8\times 5+3
Multiply both sides of the equation by 5.
15x+20y=40+3
Multiply 8 and 5 to get 40.
15x+20y=43
Add 40 and 3 to get 43.
20y=43-15x
Subtract 15x from both sides.
\frac{20y}{20}=\frac{43-15x}{20}
Divide both sides by 20.
y=\frac{43-15x}{20}
Dividing by 20 undoes the multiplication by 20.
y=-\frac{3x}{4}+\frac{43}{20}
Divide 43-15x by 20.
