Answer:
x = 10
Step-by-step explanation:
2(1+5x)-3x=72
Distribute
2 + 10x -3x = 72
Combine like terms
2+7x=72
Subtract 2 from each side
2+7x-2 = 72-2
7x = 70
Divide by 7
7x/7 = 70/7
x = 10
2(x-6)+5=20,
2x-12+5=20,
2x-7=20,
2x=27
x=27/2
OR
x= 13.5
Answer:
4a+2n+10
Step-by-step explanation:
Find anything with the same variable since 4a and 2n doesn't have the same variable we just leave it the same since 7 plus 3 is 10. So the equation looks like this: 4a+2n+10
