Solve Systems of Equations:
x + 12y = 7; x - y = 7 =======> x = 7, and y = 0
Step 1: I will try to solve your System of Equation:
x + 12y = 7; x - y = 7
Solve:
x + 12y = 7x for x:
x + 12y + -12y = 7 + -12y (Add --12y both sides):
x = -12y + 7
Substitute:
-12y + 7 for x in x - y = 7
x - y = 7
-12y + 7 - y = 7
-13y + 7 = 7 (Simplify both sides):
-13y + 7 + -7 = 7 + -7 (Add -7 both sides):
-13y = 0
-13y / -13 = 0 / -13 (Divide both sides by -13):
y = 0
Substitute:
0 for y in x = -12y + 7
x = -12y + 7
x = ( -12 )(0 ) + 7
x = 7 (Simplify both sides of Equations:):
Therefore, Answers, x = 7, and y = 0

Answer:
Step-by-step explanation:
we have
Find f(-3)
we know that
f(-3) is the value of the function f(x) for the value of x equal to -3
so
substitute the value of x=-3 in the function above to get f(-3)
1.20*2 = 2.40 + 0.60 = 3.00
1.20 + 0.60 = 1.80
1.20 per egg and 0.60 for toast

Answer:
<u>The quantity is US$ 58, which 6.5% is US$ 3.77 </u>
Step-by-step explanation:
Number = x
6.5% of x = $ 3.77
6.5% = 0.065 = 65/1,000 = 13/200 (Dividing by 5)
3.77 = 3 + 77/100 (We can't simplify 77/100)
Thus,
13/200 * x = 3 77/100
13x/200 = 377/100
13x = 754 (Multiplying by 200 at both sides)
x = 754/13 (Dividing by 13 at both sides)
<u>x = 58</u>
