# Q.9. To stitch a shirt, 2 m 15 cm cloth is needed. Out of 40 m cloth, how many shirts can be stitched and how much cloth will remain?
Number of shirts that can be stitched out of 4000 cm = $$\frac{4000}{215}$$ = 18 shirts | {} |

$7x+4y=8$
Substituting $x=0$ in the given equation, $7x+4y=8 ,$ results to \begin{array}{l}\require{cancel} 7x+4y=8 \\ 7(0)+4y=8 \\ 4y=8 \\ y=\dfrac{8}{4} \\ y=2 .\end{array} Substituting $y=0$ in the given equation, $7x+4y=8 ,$ results to \begin{array}{l}\require{cancel} 7x+4y=8 ... | {} |

# NDSolve for axisymmetric problem
I would like to solve an axisymmetric Poisson equation on a disk with FEM.
The code for Cartesian coordinates works fine:
NDSolve[{Laplacian[u[x, y], {x, y}, "Cartesian"] == x^2 + y^2, DirichletCondition[u[x, y] == 0, True]}, u, {x, y} \[Element] Disk[], Method -> "FiniteElement"]

# How do you solve 2t - 2 = 19 - t?
Jul 2, 2018
$t = 7$
#### Explanation:
Given: $2 t - 2 = 19 - t$.
Add $t$ to both sides.
$2 t + t - 2 = 19 - \textcolor{red}{\cancel{\textcolor{b l a c k}{t}}} + \textcolor{red}{\cancel{\textcolor{b l a c k}{t}}}$
$3 t - 2 = 19$
Add $2$ to both sides.
