Hello!

We can solve this system using substitution.
Since y = -3x + 5, we can substitute this into the following equation:
5x - 4(-3x + 5) = -3
Simplify:
5x - 4(-3x) - 4(5) = -3
5x + 12x - 20 = -3
Combine like terms:
17x - 20 = -3
Add 20 to both sides:
17x = 17
x = 1
Substitute to find y:
y = -3(1) + 5
y = -3 + 5
y = 2
Solution: (1, 2)
Answer:
x = 14
Step-by-step explanation:
Two lines given in the picture intersect each other at a point.
Given angles are the linear pair of angles.
Since, linear pair of the angles is supplementary,
(7x - 1)° + (6x - 1)° = 180°
(7x + 6x) + (- 1 - 1) = 180
13x -2 = 180
13x = 180 + 2
x = 
x = 14
Therefore, x = 14 will be the answer.

Step-by-step explanation:
A
note from the table that the cost increases by $15 for each package, then this is the multiplier for the cost.
let n be the number of packages , then
cost = 15n
B
to find the cost of 7 packages , substitute n = 7 into the rule
cost = 15 × 7 = $105
