Question

Solve each equation. Show or explain your method.

Answer 1

Answer:

1. x = 9

2. y = -3

Step-by-step explanation:

1.

8.88 = 4.44(x-7)

(x-7) = 8.88/4.44

(x-7) = 2

x = 2+7

x = 9

2.

5(y+2/5) = -13

5[(5y+2)/5] = -13

(5y+2) = -13

5y = -15

y = -3

Answer 2

Answer:

1. 8.88 = 4.44(x - 7)

take 4.44 on other side:

Note that: 4.44 is multiply on this side when it goes on other side it will divide by 8.88

So,

x - 7 = 8.88/4.44

x - 7 = 2

take 7 to RHS, again note: 7 is -ve on LHS when it  goes on RHS it will become +ve:

x = 2 + 7

x = 9

x is 9

2.  5(y + 2/5) = -13

same as ques.1 take 5 on other side

y + 2/5 = -13/5

take 2/5 on other side:

y = -13/5 - 2/5

take LCM:

y = (-13 - 2)/5

y = -15/5

y = -3

y is -3
