2nd one, y=2x+3
so subsitute y with 2x+3 in other equation
2x-(2x+3)=7
2x-2x-3=7
0-3=7
-3=7
false
no solution
(also, the slopes of the lines are the same and therefor they are paralell and differnet y intercepts so never intersect)
no solution

Step-by-step explanation:
Pears Cameron has = 6 pounds
roasted-pears recipe per batch = 13 pounds
How many batches can he make?
Number of batches of roasted-pear = Pears Cameron has / roasted-pears recipe per batch
= 6 pounds / 13 pounds
= 0.4615384615384 pounds
Approximately,
Number of batches of roasted-pear = 0.46 pounds
Answer:
12/22
Step-by-step explanation:
Because you add the total # of people you have which is 22 and you count the boys because it asks you the probability for boys.
1/3m-7=5
One solution was found :
m = 36
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
1/3*m-7-(5)=0
Step by step solution :
Step 1 :
1
Simplify —
3
Equation at the end of step 1 :
1
((— • m) - 7) - 5 = 0
3
Step 2 :
Rewriting the whole as an Equivalent Fraction :
2.1 Subtracting a whole from a fraction
Rewrite the whole as a fraction using 3 as the denominator :
7 7 • 3
7 = — = —————
1 3
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
m - (7 • 3) m - 21
——————————— = ——————
3 3
Equation at the end of step 2 :
(m - 21)
———————— - 5 = 0

Step 3 :
Rewriting the whole as an Equivalent Fraction :
3.1 Subtracting a whole from a fraction
Rewrite the whole as a fraction using 3 as the denominator :
5 5 • 3
5 = — = —————
1 3
Adding fractions that have a common denominator :
3.2 Adding up the two equivalent fractions
(m-21) - (5 • 3) m - 36
———————————————— = ——————
3 3
Equation at the end of step 3 :
m - 36
—————— = 0

Step 4 :
When a fraction equals zero :
4.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
m-36
———— • 3 = 0 • 3
3
Now, on the left hand side, the 3 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
m-36 = 0
Solving a Single Variable Equation :
4.2 Solve : m-36 = 0
Add 36 to both sides of the equation :
m = 36
One solution was found :
m = 36
