These are easy problems...You have to get x alone to solve for it.
First multiply the 7 out.
7x+49=5x+59
Then subtract the 49 from both sides
7x=5x+10
Then subtract the 5x from both sides
2x=10
Then divide the 2 from both sides to get the X alone
x=5
To check your answer, but 5 in for x in the original problem and answer.
7(5 + 7) = 5(5) + 59
7(12)=25 + 59
84=84
Which means x is 5

Fairly simple
First do the multiplication like this
7x+49=5x+59
Now Subtract 5x from both sides of the equasion like this
7x+49-5x=5x+59-5x
This gives you
2x+49=(5x-5x)+59
More specifically
2x+49=59
Now subtract 49 from both sides of the equasion
2x+49-49=59-49
More specifically
2x=10
Now multply both sides of the equasion by 1/2 so you figure for x
1/2*2x=1/2*10
x=5
Prove your answer by replacing 5 for the x value in the original equasion
7(5+7)=5(5)+59
Rules do insides of parentices first
7(12)=5(5)+59
84=25+59
84=84

7(x+7)=5x+59 distribute 7
7x+49=5x+59 subtract 5x from each side
2x+49=59 subtract 49 from each side
2x=10 divide by 2
x=5

7(x+7)=5x+59
7x+49=5x+59
7x-5x=59-49
2x=10
x=5
so x=5

7x - 2 (x - 2) + 5 (x + 3) = 7x - 2x + 4 + 5x + 15 strengthen what's contained in the bracket and write it out = 7x - 2x + 5x + 4 + 15 crew each of the x-es and numbers jointly = 10x + 19 subtract/upload the x-es and the numbers

7x + 49 = 5x + 59
2x = 10
x = 5
