Answer:
x=4
y=10
Step-by-step explanation:
3x +3y = 27
x - 3y = -11 (add these up so 3y will be eliminated and you'll have x only)
4x = 16
now let's eliminate x (you can put 4 instead of x though)
3x + 3y = 27
-3/ x -3y= -11 (multiple the the 2nd equation with -3 to eliminate x )
3x + 3y =27
-3x + 3y =33
6y = 60
Answer:
The number is -3
Step-by-step explanation:
Write an equation
2x+4=-10
add 4 on both sides
2x=-6
divide 2 on both sides to isolate variable
x=-3
Answer:
5, 9,13,17
Step-by-step explanation:
5 +4 +4+4
Y=11x+2 should be you answer for the slope
Solution
Switch sides so that m is on the left side
m/r = 2r
Them multiply both sides by r
mr/r = 2rr
Now simplify the equation
m = 2r^2
Therefore the equation evaluates to
m = 2r squared by 2
