700x+1900z=2500-1000y
Subtract 1000y from both sides.
700x=2500-1000y-1900z
Subtract 1900z from both sides.
700x=2500-1900z-1000y
The equation is in standard form.
\frac{700x}{700}=\frac{2500-1900z-1000y}{700}
Divide both sides by 700.
x=\frac{2500-1900z-1000y}{700}
Dividing by 700 undoes the multiplication by 700.
x=\frac{25-19z-10y}{7}
Divide 2500-1000y-1900z by 700.
1000y+1900z=2500-700x
Subtract 700x from both sides.
1000y=2500-700x-1900z
Subtract 1900z from both sides.
1000y=2500-1900z-700x
The equation is in standard form.
\frac{1000y}{1000}=\frac{2500-1900z-700x}{1000}
Divide both sides by 1000.
y=\frac{2500-1900z-700x}{1000}
Dividing by 1000 undoes the multiplication by 1000.
y=-\frac{7x}{10}-\frac{19z}{10}+\frac{5}{2}
Divide 2500-700x-1900z by 1000.
