Group Title
Match each equation in the left column with its solution in the right column.
Term:
1. 8(x + 5) = 48
2. 5(2x – 3) = 5
3. 4(x – 8) = 4
4. 3(3x + 1) = 30
Definition:
A) x = 1
B) x = 3
C) x = 2
D) x = 9
~Please help and explain if you can. I just can't seem to wrap my head around how to do it.~

Just solve each equation and then match

That's my problem. I can never get the equation right. I always mess up somewhere in the process.

Or substitute each answer instead of x for example: 8(1+5)=48 8+40=48 So x=1 and so on

Okay.. So how does (1+5) become 40? That's the part I don't understand.

Since you have bracket like this: 8(1+5) You multiply the 8 with the numbers in the bracket 8*1=8 and 8*5=40 So since you have the numbers 8 and 40 which are both positive you will get+8+40 which is equal to +48

Consider this rule so it can help you: \[a(b+c)=ab+ac\]

Ok so try to get rid of the brackets as I showed you before.

Ok. Don't I have to move the X first though?

No Just multiply the outside number with the numbers and variables in the bracket Consider also this rule:\[a(bx+c)=abx+ac\]

So you have 10x15=5 Now try solving it

And just to make sure. 4(x – 8) = 4 is D and 3(3x + 1) = 30 is B? Correct?

If you have solved any equation, you should replace your answer with the variable and perform the calculations to get it. For example replace the 2 you have got with x and try calculating it and if you get 5 which is the answer:5(2(2)3)=5 then that means that you have solved the equation correctly. Your welcome
