X plus 2y equals 8 -2x - 2y equals -10?
2y = -10y = -58 - 2x - 2(-5) = -108 - 2x + 10 = -10-2x = -10 - 182x = 28x = 14Check:2y = 8 - 2x - 2y = -102(-5) = 8 - 2(14) - 2(-5) = -10-10 = 8 - 28 + 10 = -10-10 = -20 + 10 = -10-10 = -10 = -10

Use the substitution method to solve the system of equations Enter your answer as an ordered pair 16x - 2y equals 74 2x - 2y equals 4?
16x - 2y = 74 (Eq 1) 2x - 2y = 4 (Eq 2) from Eq 2, 2y = 2x - 4 Substitute in Eq 1 16x - (2x - 4) =74 ie 16x - 2x + 4 = 74 ie 14x = 70 ie x = 5 2y = 2x - 4 = 10 - 4 = 6 y =3 Check 16 x 5 - 2 x 3 = 80 - 6 = 84 QED
X plus 2y equals 10 and 4y - 20 equals 2x?
The solution is:- x = 0 and y = 5
X plus 2y equals 8 -2x - 2y equals -10?
2y = -10y = -58 - 2x - 2(-5) = -108 - 2x + 10 = -10-2x = -10 - 182x = 28x = 14Check:2y = 8 - 2x - 2y = -102(-5) = 8 - 2(14) - 2(-5) = -10-10 = 8 - 28 + 10 = -10-10 = -20 + 10 = -10-10 = -10 = -10
How do you convert 2x equals 10-2y?
Divide both sides by 2: 2x = 10 - 2y __ __ ___ 2 2 2 x = 5 - y
How many solutions does x plus 2y equals 10 4y-20 equals 2x have?
To determine the number of solutions for the system of equations (x + 2y = 10) and (4y - 20 = 2x), we can rewrite the second equation as (2x - 4y + 20 = 0). Rearranging gives us (x = 2y + 10). Substituting this into the first equation leads to a consistent system, indicating that there is exactly one solution where the lines intersect. Thus, the system has one unique solution.
How do you do 4x 2y equals 10 and solve for y?
To solve the equation (4x + 2y = 10) for (y), first isolate (2y) by subtracting (4x) from both sides: (2y = 10 - 4x). Then, divide both sides by 2 to solve for (y): (y = 5 - 2x). Thus, the solution for (y) in terms of (x) is (y = 5 - 2x).
What kind of solution is 2x-y equals 0 and 4x-2y equals 0?
The two equations are linear.
What is 4x plus 2y equals 20 in slope-inercept form?
