The expression is 5b + 16
Add the equations: 4a + 4a - 5b + 5b = 7 + 17 ie 8a = 24 a = 3, so b = 1
b=7
3a+5b+7a=
The answer to 6b plus 7 times 5-4b plus 1 equals 38. This is taught in math.

(4, 3)
the answer
5b = 21 + 4b 5b - 4b = 21 + 4b - 4b b = 21
b= -162
5b + 3 = 10 - 3 - 3 5b = 7 5b/5 7/5 b= 1.5 There you go !
b=7
It is 9
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
No unfortunately this is not an equation. An equation must end with an equals sign. 5b + 14 is simply two terms.
5b + 5b = 2 x 5b
