The answer would be 60. By rounding, 14.2=14; 15.51=16; 14.99=15; 15.8=16.
14+15+16+16=61
Rounding: 61=60
<span> x - 4y = -5
-x + 6y = 7
---------------add
2y = 2
y = 1
</span> x - 4y = -5
x - 4(1) = -5
x - 4 = -5
x = -1
answer
x = -1 and y = 1
Here's the graph of your equation, instructions on how to plot is in the image. if there's a second line equation, you could use the method shown to plot that too, and the x and y values of the intersection point would be your answer.
you could also use algebra to simultaneously solve the two equations to obtain x and y as well, feel free to ask!
hope that helps :) sorry it's not a definite answer
The slope is the number and/ or fraction that is being multiplied by X. the Y- intercept is the +/ - of a number at the end of the equation.
