Step-by-step explanation:
the product of a number and 5
<em>n</em> - number
the product - it's multiplication
<h2><em>n · 5 = 5 · n = 5n</em></h2><h2 />
the difference of a number and 7
<em>n</em> - number
the difference - it's subtraction
<h2><em>
n - 7</em></h2>
Answer:
Y=3
Step-by-step explanation:
6x - 5 = 3x + 1
-3x -3x
————————
3x - 5 = 1
+ 5 + 5
————————
3x = 6
—— —
3 3
x = 2

Check
6(2) - 5 = 3(2) + 1
12 - 5 = 6 + 1
✔️
7 = 7
Use format y = mx + b
-15x + 5y = 20
-15x + 15x + 5y = 20 + 15x
5y = 20 + 15x
y = (20 + 15x)/5
y = 4 + 3x
y = 3x + 4
m is the slope, so 3 is the answer
