3\times 5\left(x+1\right)-7\times 2\left(y+2\right)=-42
Multiply both sides of the equation by 21, the least common multiple of 7,3.
15\left(x+1\right)-7\times 2\left(y+2\right)=-42
Multiply 3 and 5 to get 15.
15x+15-7\times 2\left(y+2\right)=-42
Use the distributive property to multiply 15 by x+1.
15x+15-14\left(y+2\right)=-42
Multiply -7 and 2 to get -14.
15x+15-14y-28=-42
Use the distributive property to multiply -14 by y+2.
15x-13-14y=-42
Subtract 28 from 15 to get -13.
15x-14y=-42+13
Add 13 to both sides.
15x-14y=-29
Add -42 and 13 to get -29.
15x=-29+14y
Add 14y to both sides.
15x=14y-29
The equation is in standard form.
\frac{15x}{15}=\frac{14y-29}{15}
Divide both sides by 15.
x=\frac{14y-29}{15}
Dividing by 15 undoes the multiplication by 15.
3\times 5\left(x+1\right)-7\times 2\left(y+2\right)=-42
Multiply both sides of the equation by 21, the least common multiple of 7,3.
15\left(x+1\right)-7\times 2\left(y+2\right)=-42
Multiply 3 and 5 to get 15.
15x+15-7\times 2\left(y+2\right)=-42
Use the distributive property to multiply 15 by x+1.
15x+15-14\left(y+2\right)=-42
Multiply -7 and 2 to get -14.
15x+15-14y-28=-42
Use the distributive property to multiply -14 by y+2.
15x-13-14y=-42
Subtract 28 from 15 to get -13.
-13-14y=-42-15x
Subtract 15x from both sides.
-14y=-42-15x+13
Add 13 to both sides.
-14y=-29-15x
Add -42 and 13 to get -29.
-14y=-15x-29
The equation is in standard form.
\frac{-14y}{-14}=\frac{-15x-29}{-14}
Divide both sides by -14.
y=\frac{-15x-29}{-14}
Dividing by -14 undoes the multiplication by -14.
y=\frac{15x+29}{14}
Divide -29-15x by -14.
