Solve for y.<br><br> −140=18+4(5y−2)
vagabundo [1.1K]

For this case we have the following equation:

-140 = 18 + 4 (5y-2)

From here, we must clear the value of y.

For this, we follow the following steps:

1) Distributive property:

-140 = 18 + 20y-8

2) Variable terms on one side of the equation and constant terms on the other side of the equation:

20y = -140 - 18 + 8

3) Algebraically add the constant terms:

20y = -150

4) Pass the number 20 to divide:

y = -\frac{150}{20}\\y = -7.5

Answer:

The value of y is given by:

y = -7.5

Plz help me agh! It’s linear stuff
kherson [118]

Answer:

(1/2)x - y = -2

General Formulas and Concepts:

<u>Pre-Alg</u>

  • Equality Properties

<u>Alg I</u>

Slope-Intercept Form: y = mx + b

  • m - slope
  • b - y-intercept

Standard Form: Ax + By = C

Step-by-step explanation:

<u>Step 1: Define equation</u>

Slope-Intercept Form: 2 + (1/2)x = y

<u>Step 2: Find Standard Form</u>

  1. Rewrite:                                        y = (1/2)x + 2
  2. Subtract 1/2x on both sides:       y - 1/2x = 2
  3. Factor negative:                          -(1/2x - y) = 2
  4. Divide both sides by -1:               1/2x - y = -2
