Answer:
X = 3
Step-by-step explanation:
Given the expression :7x - 3 = 18
To obtain the solution set ; we solve for X in the equation ;
7x - 3 = 18
Add 3 to both sides
7x - 3 + 3 = 18 + 3
7x = 21
Divide both sides by 7
7x / 7 = 21 / 7
x = 3
Hence, x = 3
Answer:
Step-by-step explanation:
10x + 14y = 18.....reduce by dividing everything by 2 and u end up with 5x + 7y = 9
notice how both equations are now the same....means same line.....this means ur solution is : INFINITE SOLUTIONS
$43.25 - $7.00 = $36.25

Answer:
5 pens = 15$ and 4 pencils = 4$
Step-by-step explanation:
7-3=4, so 4 pens is 12$
12/4 = 3, so 1 pen = 3$
Remove the pens from the equation
7x3=21
24-21=3
3/3=1, so each pencil costs 1$
The side lengths are congruent, because the triangle is only being moved
