How kany doulutions does this equation have 25 - 4x=15-3x+10-x
natima [27]
Since it's a one-variable equation, it has only one solution:

25 - 4x = 15 - 3x + 10 - x

25 - 4x + x = 15 - 3x + 10

25 - 3x = 15 - 3x + 10

- 3x = 15 - 3x + 10 - 25

- 3x = 15 - 3x - 15

- 3x + 3x = 15 - 15

0 = 15 - 15

0 = 0




Hope it helped,

PLEASE ANSWER ASAP!!!!!! I WILL LOVE FOREVER LOL!!!
const2013 [10]

Point-slope form:  y - y₁ = m(x - x₁)

(m is the slope, (x₁, y₁) is the point you are given that is on the line)

You know:

m = 5

(x₁, y₁) = (-2, -3)         So substitute/plug it into the equation

y - y₁ = m(x - x₁)

y - (-3) = 5(x - (-2))   (two negative signs cancel each other out and become positive)

y + 3 = 5(x + 2)    Your answer is A

similarly

9,40,41 also is a Pythagorean triplet
