Assuming your asking for two sets of systems of equations.

#1: {y,x}={-1,-1}

Steps:

Solve by Substitution :

// Solve equation [2] for the variable  x

[2]    x = -y - 2

// Plug this in for variable  x  in equation [1]

[1]    y - 4•(-y -2) = 3

  [1]    5y = -5

// Solve equation [1] for the variable  y

  [1]    5y = - 5

 [1]    y = - 1

// By now we know this much :

  y = -1

   x = -y-2

// Use the  y  value to solve for  x

x = -(-1)-2 = -1

Solution :

{y,x} = {-1,-1}

2: {y,x}={3,-1}

Steps:

Solve by Substitution :

// Solve equation [2] for the variable  x

 [2]    x = -y + 2

// Plug this in for variable  x  in equation [1]

 [1]    y + 6•(-y +2) = -3

  [1]    -5y = -15

// Solve equation [1] for the variable  y

[1]    5y = 15

[1]    y = 3

// By now we know this much :

y = 3

x = -y+2

// Use the  y  value to solve for  x

x = -(3)+2 = -1

Solution :

{y,x} = {3,-1}

Of the 240 sandwiches Joanna makes 20% are tuna sandwiches and 40% are jam sandwiches, and the rest are egg salad sandwiches.How
nikitadnepr [17]
240 = 100%
so 10% = 24 sandwiches 
all - (tuna) - (jam) = egg
100% - 20% - 40% = 40%
40% = 10%*4
40% = 24*4 = 96

the answer is 96 egg salad sandwiches

Four families went out for lunch. The total food
dybincka [34]

Answer:

Each family spent about 34.25 on dinner

Step-by-step explanation:

$167 - $30 (tip) = 137

137 ÷  4 (for each family) = 34.25

BUT

if each family is seperate than they each spent about 11.75 on dinner

167 - (30 x 4) = 47

47 ÷  4 = 11.75

I'm pretty sure the first one is the answer though
