Viktor [21]
Y = 4x + 3  ---------(1)
y = -x - 2    ---------(2)

Subtract (2) from (1), you get
0 = 5x + 5
⇒ 5x + 5 = 0
⇒ 5x = -5
⇒ x = -5/5 = -1
y = -(-1) - 2 = -1

Answer is (-1,-1)

What is −4(−5x+2)−3x−5= -30
alexandr1967 [171]

Answer:

x = -1

Step-by-step explanation:

Step 1: Write equation

-4(-5x + 2) - 3x - 5 = -30

Step 2: Solve for <em>x</em>

<u>Distribute -4:</u> 20x - 8 - 3x - 5 = -30

<u>Combine like terms:</u> 17x - 13 = -30

<u>Add 13 on both sides:</u> 17x = -17

<u>Divide both sides by 17:</u> x = -1
