Solve: y = x - 4
y= 6x - 10

x = 1.2; y = -2.8

Step-by-step explanation:

y = x -4

y = 6x -10

y -x = -4

y -6x = -10

Subtracting the equations:

5x = 6

x = 6/5 or 1.2

Substitute x = 1.2

y = 1.2 - 4

y = -2.8 or -14/5

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
