Linear equations are a type of equation that has a linear relationship between two variables, and they can often be used to solve word problems. In order to solve a word problem involving a linear equation, you will need to identify the variables in the problem and determine the relationship between them.
By the problem, a delivery company charges a base fee of \$5 plus \$2 per mile for delivering packages. a) Thus, the cost equation is: y = 2x + 5 b) After plotting the equation y = 2x + 5, we get the required graph. c) Substituting x = 6 into the equation, y = 2(6) + 5 ⇒ y = 12 + 5 ⇒ y = 17 Thus, the cost for a 6-mile delivery is \$17.
Translate to a Linear Equation. Sometimes, the trick to solving a word problem will be to translate it into a linear equation. To clue you in, linear equation word problems usually involve some sort of rate of change, or steady increase (or decrease) based on a single variable.If you see the word rate, or even "per" or "each", it's a safe bet that a word problem is calling for a linear equation.

Multiply both sides of the equation by 42 to get rid of the denominators 6 and 7. 42(ˣ⁄₆) = 42(ˣ⁄₇ + 1) 7x = 42(ˣ⁄₇) + 42. 7x = 6x + 42. x = 42. The number is 42. Problem 6 : Three times of my age 5 years ago is equal to 5 less than two times of my age 5 years hence. How old am i now? Solution : Let x be the your present age.

Problem 4 : A manufacturer produces 80 units of a product at a cost of $22000 and 125 units at a cost of $28750. Assuming the cost curve to be linear, find the equation of the cost curve and then use it to estimate the cost of 95 units. Solution : Since the cost curve is linear, its equation will be. y = Ax + B. (Here y = Total cost, x = no. of ...
