Answer 1

Explanation:

Each equation asks for x . So let's solve it in a way so that at the end remains x = ,then the rest equation.

So first one,

1. a(x+b)=c

ax + ab = c

ax = c - ab

x = (c - ab ) / a

Now we can write that in two ways:

i. We already got the answer for the 2nd blank which is c - ab / a

ii. If we rearrange it so that there is a minus sign, it would be like: c/a  - b

Try solving the rest 3 by your self to make sure you understood them. Then scroll down to match the answers.

2. 8(x + a) = b

8x + 8a = b

8x = b - 8a

x = (b-8a)/ 8

First blank for 2nd equation: x = b/8  - a

Second blank: x = b - 8a  /  8

3. a(x - 9) = b

ax - 9a = b

ax = b + 9a

x = (b + 9a) / a

First blank for 3rd equation: x = b/a + 9

Second blank: x = b+9a  /  a

4. c(2 + x ) = 7

2c + cx = 7

cx = 7 - 2c

x = (7 - 2c) / c

First blank for 4th equation: x = 7/c  - 2

Second blank: x = 7 - 2c  / c

Do let me know if it's correct! <3
