No unfortunately this is not an equation. An equation must end with an equals sign. 5b + 14 is simply two terms.

4a - 5b = 74a +5b = 17From the first equation:4a = 7 + 5bsubstitute this value in the second equation:7 + 5b + 5b = 177 + 10b = 1710b = 10b = 1Now,solve for a :4a - 5(1) = 74a = 7 + 54a = 12a = 3

-5b - 6 = -11Add 6 to each side of the equation:-5b = -5Divide each side by -5 :b = 1

Add the equations: 4a + 4a - 5b + 5b = 7 + 17 ie 8a = 24 a = 3, so b = 1

5b-15 = -10

(4, 3)

If: 5b = 30 Then: b = 6

5b + 15 = 5(b + 3)

The answer is 7.

really????? what grade are you in??? 5b b=3 so you plug in 3 for b giving you 5(3) then you multiply because its multiplication and you get 15

the answer

5b = 21 + 4b 5b - 4b = 21 + 4b - 4b b = 21
