Step-by-step explanation:
No solutions. Both equations on the graph are parallel from each other, making it impossible to find a solution. When both lines intersect, that means a ordered pair (x) and (y) work as valid solutions to the equations.
Step 1 rewrite the equation
step 2 30/5= 6
step 3 x=6
1 solution
<span>Abdul used a probability simulator to roll a 6-sided number cube and flip a coin 100 times. The results are shown in the tables below:

Using Abdul's simulation, what is the probability of rolling a 2 on the number cube and the coin landing heads up?
Answer:
x = -8
y = 7
Step-by-step explanation:
5x + 7y = 9
2x - 3y = -37
1.) First, multiply each side to match either y-values or x-values. (In this example, we'll use match x-values)
10x + 14y = 18 (multiplied by 2)
10x - 15y = -185 (multiplied by 5)
2.) Then, subtract the entirety of one equation to isolate the y-value.
10x + 14y = 18
-10x + 15y = 185
3.) Add and subtract values and divide to find y.
29y = 203
y = 7
4.) Plug-in y to solve for x into one equation, or repeat steps 1-3.
15x + 21y = 27
14x - 21y = -259
29x = -232
x = -8
