Linear equations for real world problems

NettetIn Algebra, linear equations in one variable can have either one solution (i.e. $x=3$), infinitely many solutions (i.e. $2x+6=3(x+2)-x$), or no solution (i.e. $x+3=x+5$). What would be some real-life situations where an equation would end up being a contradiction or identity and that would reveal something about what the equation represents? NettetMr Slope Guy. Hello Math Teachers! Hit the slopes with these y = mx + b Word Problems on Slope-Intercept. This activity contains 15 questions matching Slope Intercept Equations to real-world situations, adding relevancy for your students. There are also 12 questions matching equations to graphs.

Nettet6. okt. 2024 · We therefore get the equation: x + 9 = 3 x − 7. We solve for x by adding 7 on both sides of the equation: x + 16 = 3 x. Then we subtract x: 16 = 2 x. After dividing by 2, we obtain the answer x = 8 The following word problems consider real world … NettetAnother example of a system of equations solvable by substitution is; x + 3y = 9 2x - 5y = 27. The next class of systems of equations that I will present are solvable by the addition/subtraction method. An example would be; 2x + 4y = 33 2x + 6y = 54. In this system, the coefficient of x is the same in both equations.
