Question

(5) Check whether the value given in the brackets is a solution to the given equation or not
(a) 4p − 3 = 13 (p = −4) (b) 4p- 3=13 (p= - 4)
(6) Solve by trial and error method: 3m – 14 = 4
(7) Write the equations for the given statements.
(a) If you take away 8 from 8 times y, you get 90

(b) The number b divided by 5 gives 6
(8) Give the steps you will use to separate the variable and then solve the equation.
5m+7=17

Answer 1

Answer:

i also want this answer so can i follow you

Answer 2

Step-by-step explanation:

5(a) 4p-3 = 13

(4 X(-4))-3 = 13

(-16)-3 = 13

-19 = 13

Number 5:p is not equal to -4

6) 3m - 14 = 4

   [Collect like terms]

3m = 4 + 14

3m = 18

[Divide both sides of the equation by 3]

m = 18 ÷ 3

m = 6

7(a) 8y -8 = 90

b) $\frac{b}{5}$ = 6

8) 5m+7 = 17

[Collect like terms]

5m = 17 - 7

5m = 10

[Divide both sides of the equation by 5]

m = 10 ÷ 5

m = 2
