-2y + 5z = -3
y = -5x - 4z - 5
x = 4z + 4
-2(-5(4z + 4) - 4z - 5) + 5z = -3
-2(-20z - 20 - 4z - 5) + 5z = -3
-2(-20z - 4z - 20 - 5) + 5z = -3
-2(-24z - 25) = -3
48z + 50 = -3
<u> - 50 - 50</u>
<u>48z</u> = <u>-53</u>
48 48
z = -1⁵/₄₈
x = 4(-1⁵/₄₈) + 4
x = -4⁵/₁₂ + 4
x = ⁵/₁₂
y = -5(⁵/₁₂) - 4(-1⁵/₄₈) - 5
y = -2¹/₂ + 4⁵/₁₂ - 5
y = 1¹¹/₁₂ - 5
y = -3¹/₂
(x, y, z) = (⁵/₁₂, -3¹/₂, -1⁵/₄₈)

The number is 10.
5*10=50
50+5=55
6*10=60
60-5=55
Answer:
Step-by-step explanation:
5x-2y-12=0
5x-2y+12-12=0+12
5x-2y=12
5x-5x-2y=12-5x
-2y=12-5x
(-2y)/-2=(12-5x)/-2
y=5/2x-6
slope= 5/2x up 5 over 2
y-intercept is -6
Well.. General form is Ax+by+c=0
So this is not in general form
