Question

Q1) Write each of the following statements as an equation:
(a) A number increased by 7 is 15.
(b) Four times a number x is 68.
(c) A number y divided by 5 is 9.
(d) 8 subtracted from twice a number is 24.
(e) 7 times a number is 4 more than the number.
Q2) Solve each of the following equations:
(a) 7x + 2 = 2x – 18
(b) 2(2y - 3) = 5(y – 4)
​

Answer 1

a)x+7=15

b)4x=68

c)5/y=9

d)2x-8=24

e)7x=x+4

2.7x-2x=-18-2

=>5x=-20

=>x=-4

b)6y-6=5y-20

=>6y-5y=-20+6

=>y=-14

Answer 2

Answer:

Q1)

(a)x+7=15

(b)4x=68

(c)y/5=9

(d)2x-8=24

(e)7x=4+x

Q2)

(a) 7x+2=2X-18

7x-2 x= -2-18

5x = -20

x = -20 / 5

x = -4

(b) 2 (2y-3) = 5(y-4)

4y-6=5y-20

5y-4y =-6+20

y=14
