Just sub in ANY number for x and solve for y
5x + 7y = 19.....lets say x = 0
5(0) + 7y = 19
7y = 19
y = 19/7...so when x = 0, y = 19/7.....(0,19/7)
5x + 7y = 19....lets say x = 1
5(1) + 7y = 19
5 + 7y = 19
7y = 19 - 5
7y = 14
y = 14/7
y = 2.....so when x = 1, y = 2......(1,2)
5x + 7y = 19.....lets say x = 3
5(3) + 7y = 19
15 + 7y = 19
7y = 19 - 15
7y = 4
y = 4/7...so when x = 3, y = 4/7.....(3,4/7)
Answer:

Step-by-step explanation:
Equation: 
Step 1: Balance both parts of the equation.




Step 2: Reduce 14 from both parts of the equation.


Step 3: Split both sides by 10, because
.


Therefore, x = -1.
The measurement of angle x is 40°. these two triangle are congruent so their sides share the same length and their angles share the same degrees
Answer:
100
Step-by-step explanation:
I will try my best to assist you with your question ,
First we must divide the amount by 2
334/2 = 167
Now we add 16
167 + 16=183
So, the girl spent $183
Wow, she is spoiled!
Hope I helped!
Good Luck!
