Answer:
x = 16
Step-by-step explanation:
3x - 10 = 2(x+3)
<em>First step is solve this:</em>
<em>2(x+3) = 2*x + 2*3 = 2x + 6</em>
then:
3x - 10 = 2x + 6
3x - 2x = 6 + 10
x = 16
Check:
3*16 - 10 = 2(16+3)
48 - 10 = 2*19 = 38
The elevation of the volcano to the ocean floor is 15 but the from on the volcano from the floor it is 10 the ocean is a basic -5

The next whole number following a whole number w: w + 1
<span>4x – 5y = –18 (1st)
3x + 2y = –2 (2nd)
Multiply 1st equation by 2 and 2nd equation by 5
</span>4x – 5y = –18 (1st) (mul. 2)
3x + 2y = –2 (2nd) (mul. 5)
8x - 10y = - 36
15x + 10y = - 10
-----------------------add
23x = - 46
x = -2
3x + 2y = –2
3(-2) + 2y = –2
-6 + 2y = -2
2y = 4
y = 2
