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 value of x in the proportion is 5 and 2/5
So we factor out the number and find the number in both numbers so
117=3*3*13
351=3*3*13*3
so the greatest common factor of 117 and 351 is 3*3*13=117
35=7*5
149=prime=149 (prime means no whole factors)
