Consider the following pair of equations:
Aloiza [94]
Y = 3x + 3 this is equation 1
y = x -1 this is equation 2
since equation 1 and 2 already defined y in terms of x, we're just gonna substitute y into the other equation. as 2 is shorter I'm going with that today
x - 1 = 3x +3
-1 - 3 = 3x - x
-4 = 2x
x = -2
now we've got x just sub it in equation 2
y = -2 -1
y = -3
so the answer is (-2,-3)

What is the value of x in the equation 3/4(14x+8)-(1/2x+2)=3/8(4-x)-1/4
Sedaia [141]

Answer:

-37/68

Step-by-step explanation:

3/4(14x+8)-(1/2x+2)=3/8(4-x)-1/4

(21/2x+6)-(1/2+2)=(3/2x-3/8)-1/4

(21/2x-1/2x)+(6-2)=3/2x-3/8-1/4

10x+4=3/2x-5/8

37/8=-17/2x

37/8 (2)=-17/2x(2)

37/4=-17x

37/68=-x

-37/68=x

What is the value of c?<br> 14 = - 2c - 6 - 3c
Neporo4naja [7]

Answer:

c = -4

Step-by-step explanation:

Step 1: Write equation

14 = -2c - 6 - 3c

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

  1. Combine like terms: 14 = -5c - 6
  2. Add 6 on both sides: 20 = -5c
  3. Divide both sides by -5: c = -4

Step 3: Check

<em>Plug in c to verify it's a solution.</em>

14 = -2(-4) - 6 - 3(-4)

14 = 8 - 6 + 12

14 = 2 + 12

14 = 14
