Find the value of a in the equatuion 5 over a+3 =3 over a-2

9.5

Step-by-step explanation:

5/(a+3)=3/(a-2)

5(a-2)=3(a+3)

5a-10=3a+9

5a-3a=9+10

2a=19

a=9.5

M

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
