Answer:
x=7
Step-by-step explanation:
Since (3x+10)+(x-2)= 36, that means (4x+10-2)=36
To solve, first combine like terms:
4x+10-2= 36 -------- 4x+8=36
Then subtract 8 from both sides:
4x+8= 36 ---------- 4x= 28
Then divide:
[tex]\frac{4x}{4}[/tex]=[tex]\frac{28}{4}[/tex]
Simplify:
x=7
Check you work:
21+10= 31
7-2= 5
31+5= 36
Hope this helps! :)
