$30+$25(x)=$180
U can solve by isolating da variable. Subtract 30 on both sides. Given u:
$25(x)=$150
Now u divide 25 to both sides. Given u:
x=6 days
Answer : c= 14
cross multiply
45 *8 = 360
divide
360/15 = 24
Move variable to the left. -w= -10+ 4W
-w-4W =-10
Collect like terms
-5w=-10 divide both sides by 5
Answer:
3x +5y = 10
Step-by-step explanation:
Multiply by 5 to make all numbers integers. Then add the opposite of the x-term to separate variable terms from the constant.
5y = -3x +10 . . . . multiply by 5
3x +5y = 10 . . . . add 3x

<em>Comment on standard form</em>
The standard form of a linear equation is ...
ax +by = c
where a, b, c are mutually prime integers, and a≥0. If a=0, then b>0.
