What is a solution to the following system of equations using substitution -5x plus y equals -5?
-10
Which points are on the line given by the equation y5x?
If you mean: y = 5x then it has a slope of 5 and passes through the origin of (0, 0)
What is the y-intercept of the line given by the equation y5x 16?
If you mean: y = 5x+16 then the y intercept is 16 and the slope is 5
Solve the simultanius equations 3x - y equals 11 and x plus y equals 5?
3x-y = 11 x+y = 5 Add both equations together: 4x = 16 Divide both sides by 4 to find the value of x: x = 4 Substitute the value of x into the original equations to find the value of y: Therefore: x = 4 and y = 1
7x - 5y equals 76 4x plus y equals 55?
To solve this system of equations, we can use the method of substitution or elimination. Let's use the substitution method. From the second equation, we can express y as y = 55 - 4x. Substitute this expression for y in the first equation: 7x - 5(55 - 4x) = 76. Simplify this equation to solve for x. Then, substitute the value of x back into one of the original equations to find the value of y.
