What is the solution of the given equation?
3y+42+2y-53=312
y=1
y=6
y=7
y=13
Finding the solution for the given equation:
3y+42+2y-53=312⇒33y+4+22y-56=312⇒9y+12+4y-106=312⇒13y+26=312⇒213y+2=631⇒26y+4=186⇒26y=182⇒y=18226⇒y=7
Therefore the value of y=7
Hence, the correct answer is option C.
Check whether the value given in the brackets is a solution to the given equation or not:
(a) n + 5 = 19 (n = 1) (b) 7n + 5 = 19 (n = − 2)
(c) 7n + 5 = 19 (n = 2) (d) 4p − 3 = 13 (p = 1)
(e) 4p − 3 = 13 (p = − 4) (f) 4p − 3 = 13 (p = 0)
Solution of the equation 4x+5[x-{3-2(x+1)}]=2+3x is
