Solve step by step: 25/6-4x = -9x=5/6

1 answer:

5 0

Simplifying 5(6 + -4x) = 25 (6 * 5 + -4x * 5) = 25 (30 + -20x) = 25 Solving 30 + -20x = 25 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-30' to each side of the equation. 30 + -30 + -20x = 25 + -30 Combine like terms: 30 + -30 = 0 0 + -20x = 25 + -30 -20x = 25 + -30 Combine like terms: 25 + -30 = -5 -20x = -5 Divide each side by '-20'. x = 0.25

Determine the value of B such that the line defined by 8x + By + 92 = 0 passes through the point (-4,12).

zvonat [6]

8x + By + 92 = 0

(-4; 12) ⇒ x = -4; y = 12

subtitute

8 · (-4) + 12B + 92 = 0
-32 + 12B + 92 = 0
12B + 60 = 0 |subtract 60 from both sides
12B = -60 |divide both sides by 12

B = -5

D is the correct answer
x+5=10: subtract 5 from both sides the 5 will cancel out leaving x=5
x+5=10
-5 -5
x=5
