For X, I assume.
7X - 10 = 4X + 11
subtract 4X from each side
7X - 4X - 10 = 4X - 4X + 11
3X - 10 = 11
add 10 to each side
3X - 10 + 10 = 11 + 10
3X = 21
divide both sides by 3
X = 7
check
7(7) - 10 = 4(7) + 11
49 - 10 = 28 + 11
39 = 39
checks
y = (11-4x)/5
x=2.75 This follows from the equation (4x - 3) + 11 = 19 and 4x = 11
7
2x + 33 = 4x + 11 -11 -11 2x + 22 = 4x -2x -2x 22 = 4x Divide each side by 4 x = 5.5
(-1, 2)
y = (11-4x)/5
-11
= 3
x=2.75 This follows from the equation (4x - 3) + 11 = 19 and 4x = 11
7
2x + 33 = 4x + 11 -11 -11 2x + 22 = 4x -2x -2x 22 = 4x Divide each side by 4 x = 5.5
(-1, 2)
4x - 7 = 2x + 15 4x = 2x +222x = 22x = 11
It is an equation and the value of x is 4
Y = x2 + 4x + 11OK. That's very interesting.Is there a question ?
x= -11
The value of x is -4
