Question

solve the following equation and check whether it is correct or not.
a)3x+5=27
b)7x=49
c)4+5(m-1)=34
d)x/3 +5=8
e)3/2y +7=20
please help​

Answer 1

Answer:

$3x + 5 = 27$

$3x = 27 - 5 \\3x = 22 \\ x = 22 \div 3$

$7x = 49$

$x = 49 \div 7 \\ = 7$

Answer 2

Step-by-step explanation:

A. 3x+5=27

x=22/3

put value of x in eq.

3×22/3 +5=27

→ 27=27

B. 7x =49

x=7

put value of x in eq.

7×7 = 49

49 = 49

C. 4+5(m-1)=34

→ m-1= 30/5

→m= 7

put value of m in eq.

4+ 5(7-1)=34

34 =34

D. x/3+5=8

x= 1

put value of x in eq.

1/3+5=8

16/3 ≠ 8

E. 3/2y +7 =20

3/2y =13

y= 26/3

put value of x in eq.

3/2×26/3 +7 = 20

13 +7 = 20

20= 20
