Can someone help me with these two
LenaWriter [7]

Answer:

The first equation answer is 10

And the second one 6

Step-by-step explanation:

The first equation

2/5 x +3= 2/3x +1/3

2x + 15/5 = 6x+3/9 the cress cross

9(2x + 15) = 5(6x + 3)

18x + 135 = 30x +15

135-15 = 30x - 18x

120 = 12x

120/12 =12x/12

10 = x

X =10

The second one

-2.6b +4 =0.9b - 17

-2.6b - 0.9b = - 17 - 4

-2.6b + (-0.9b) = - 17 + (-4)

-3.5b = - 21

-3.5b/-3.5 = - 21 /-3.5

B= 6
