Question

Solve the following equation and check the answer
a) 4+5(x-1)=4
4+5 x-5 = 34
5x-1 =34
5x =34+1
x= 35÷5 = 7
Check the answer
L.H.S.
4+5(x-1)
4+5(7-1)
4+5×6
4+30=34
L.H.S. = 34
R.H.S. = 34
Hence, L.H.S. = R.H.S.


Like that solve these equation

a) 3 (y+1)-2(y+1)= 5
b) 4(2x-3)+5(3x-4)=14
c)
$\frac{y + 19}{5} = 8$
d)
$\frac{x}{6} + 5 = \frac{x}{3} + \frac{x}{4}$

Answer 1

Answer:

a) y=4

Step-by-step explanation:

3y-3-2y-2=5

= 3y-2y+3-2=5

= y=5-1

= y=4

LHS

=3(y+1)-2(y+1)

=3y+3-2y-2

=3y-2y+3-2

=y+1

=4+1

=5
