Answer:
x = 22, y = -4
Step-by-step explanation:
x + 6y = -2 --- Equation 1
-x = 3y - 10 --- Equation 2
Equation 2 ×(-1): x = -3y + 10 --- Equation 3
Substitute x = -3y + 10 into Equation 1:
x + 6y = -2
-3y + 10 + 6y = -2
3y + 10 = -2
3y = -2-10
= -12
y = -12 ÷ 3
y = -4
Substitute y = -4 into Equation 3:
x = -3y + 10
x = -3(-4) + 10
= 12 + 10
x = 22
Are you looking for the name of the place value? If you are the answer is ten thousands. If that isn’t what you’re looking for, I need more information.
There are infinitely many solutions of the system of equations, x + y = 1
and 2x + 2y = 2
Step-by-step explanation:
We need to find how many solutions are there to the system of equations.
Solving:
Multiply equation (1) with 2 and subtract with equation(2)
Since our answer is 0=0 so, there are infinitely many solutions.

Answer:
2 * sqrt(61)
Step-by-step explanation:
a = 10
b = 12
c = ?
c^2 = a^2 + b^2
c^2 = 10^2 + 12^2
c^2 = 100 + 144
c^2 = 244
c^2 = 4 * 61
sqrt(c^2) = sqrt(4) * sqrt(61)
c = 2 * sqrt(61)
Do 16-9 which equals 7, then (7)^11=77 1.=77
this one add 3+4 which equals 7 then do 7^2= 49 then 4x49=196 2.=196
