5b+6=32-8b
Since -8b contains the variable to solve for, move it to the left-hand side of the equation by adding 8b to both sides.
5b+6+8b=32
Since 5b and 8b are like terms, add 8b to 5b to get 13b.
13b+6=32
Since 6 does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 6 from both sides.
13b=-6+32
Add 32 to -6 to get 26.
13b=26
Divide each term in the equation by 13.
(13b)/(13)=(26)/(13)
Simplify the left-hand side of the equation by canceling the common terms.
b=(26)/(13)
Simplify the right-hand side of the equation by simplifying each term.
b=2

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 = 21 + 4b 5b - 4b = 21 + 4b - 4b b = 21
b= -162
