keeping in mind that standard form for a linear equation means
• all coefficients must be integers, no fractions
• only the constant on the right-hand-side
• all variables on the left-hand-side, sorted
• "x" must not have a negative coefficient


For the answer tot he question above, let the number of t-shirts are represented by 't'
number of sweaters are represented by 's'
cost of 1t=10 and cost of 1s=20 so
10t+20s=2000 or (factor out the 10 if you want to simplify)
10(t+2s)=10(200)
divide both sides by 2
t+2s=200
