10x+19y=3420
Multiply both sides of the equation by 190, the least common multiple of 19,10.
10x=3420-19y
Subtract 19y from both sides.
\frac{10x}{10}=\frac{3420-19y}{10}
Divide both sides by 10.
x=\frac{3420-19y}{10}
Dividing by 10 undoes the multiplication by 10.
x=-\frac{19y}{10}+342
Divide 3420-19y by 10.
10x+19y=3420
Multiply both sides of the equation by 190, the least common multiple of 19,10.
19y=3420-10x
Subtract 10x from both sides.
\frac{19y}{19}=\frac{3420-10x}{19}
Divide both sides by 19.
y=\frac{3420-10x}{19}
Dividing by 19 undoes the multiplication by 19.
y=-\frac{10x}{19}+180
Divide 3420-10x by 19.
