60 = −2(−10 − 4x)
what is the answer show step by step

x = 5

Step-by-step explanation:

first, divide both sides.

30 = -(-10 - 4x)

then, remove the parenthesis.

30 = 10 + 4x

them, move the terms.

=4x = 10 - 30

finally, divide both sides.

-4x = 20

solution: x = 5

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
