Explanation:
1.7m + 2(m + 1) = 9m + 5
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
7*m+2*(m+1)-(9*m+5)=0
(7m + 2 • (m + 1)) - (9m + 5) = 0
-3 = 0
Solve : -3 = 0
This equation has no solution.
A a non-zero constant never equals zero.
2.4m+2(m+1)=9m+5
m=−1
Pull out like factors :
-3m - 3 = -3 • (m + 1)
-3 • (m + 1) = 0
Solve : -3 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solve : m+1 = 0
Subtract 1 from both sides of the equation :
m = -1
