Z/3+10=-7/10
multiply both sides
10z + 300 = -21
move the constant to the right
10z= -21 - 300
Calculate
10z = -321
divide both sides ^^
answer : z=-321/10
11 - 19m = -16m -16 subtract 11 on both sides, and you get -19m = -16m -27. Then you add 16m to both sides, so its -3 = -27, and once you divide both sides by -3, it equals m = 9 :)
C = (5n + 40)/9
Multiply by 9 on both sides
9C = 5n + 40
Subtract 40 from both sides
9c - 40 = 5n
Divide both sides by 5
9c/5 - 40/5 = n
n = (9/5)c - 8
Answer:
y = - 2x + 17
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 2, then
y = - 2x + c ← is the partial equation
To find c substitute (6, 5) into the partial equation
5 = - 12 + c ⇒ c = 5 + 12 = 17
y = - 2x + 17 ← equation of line
