If Dee bought a sweater and a shirt for 40 dollars but the sweater cost 12 more than the shirt how much did the shirt cost?
x =shirt
y =sweater
shirt + sweater = $40
x + y = 40
shirt + 12 = the price of the sweater (price of the sweater is $12 more than the shirt)
x + 12 = y
x + y = 40
x + (x + 12) = 40
2x + 12 = 40
2x + 12 - 12 = 40 - 12
2x = 28
2x / 2 = 28 / 2
x = 14
x = shirt = $14
IF...
shirt + sweater = $40
x + y = 40
14 + y = 40
14 + y - 14 = 40 - 14
y = 26
y = sweater = $26

The price of a sweater is 5 less than twice the price of a shirt If four shirts and three sweaters cost 275 find the price of each shirt and each sweater?
We are given two pieces of information here:The price of a sweater is $5 less than twice the price of a shirt.Four shirts and three sweaters cost $275We can express each of these terms mathematically, and use them together to solve the overall problem. First, we'll need some definitions:Let s = "sweater"let t = "shirt"We're told then:s = 2t - 54t + 3s = 275We can take those then, and eliminate with substitution. The first equation already handily gives us a definition of s relative to t, so let's plug that in to the second equation:4t + 3s = 2754t + 3(2t - 5) = 2754t + 6t - 15 = 27510t = 275 + 1510t = 290t = 29So the cost of one shirt is 29$We can then take that and plug it into one of the original equations to get the price of a sweater:s = 2t - 5s = 2(29) - 5s = 58 - 5s = 53So we now know the price of both. To state them more formally:The cost of one shirt is ridiculous.The cost of one sweater is absolutely obscene.
