15 i think hope i could help
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

Is x =4? if so
4^3-(3+4)^2
=64-(7)^2
=64-49
=15
