you should really do your own homework. but i will post the answer to help teach you. perhaps you can do the next ones on your own.
1.
2(2x-17) +4 = -3(3+x)
4x -34 +4 = -9 -3x
4x -30 = -9-3x
add 3x to both sides and you get
7x - 30 = -9
add 30 to both sides (you always do opposite of the sign given on the side you are trying to move it from)
7x = 21
divide both sides by 7 to x
therefore x = 3
2.
5x +7 = 22
subtract 7 from both sides
5x = 15
divide 5 from both sides
x = 3

1) 2 (2X -17) + 4 = -3(3 + x)
4x - 34 + 4 = -9 -3x
4x - 30 = -9 - 3x add 9 to both sides
4x - 21 = -3x add 3x to both sides
7x - 21 = 0 divide both sides by 7
x = 3
2) 5x + 7 = 22 subtract 7 from both sides
5x = 15 divide both sides by 5
X = 3

1) 2(2x - 17) + 4 = -3(3+x)
4x - 34 + 4 = -9 + -3x
9 - 34 + 4 = -4x + -3x
-21 = 12x
-1.75 = x
2) 5x + 7 = 22
5x = 22 - 7
5x = 15
x = 3
((NOTE: I might be completely wrong with #1, but I'm fairly confident #2 is correct.

1) 2(2x-17) +4 = -3(3+x)
4x-34+4= -9 +-3x You factor then,
4x-31=-9 + -3x You add up common terms then,
x-31= -9 Add 3x to both sides
x=22 add 31 to both sides
2) 5x +7=22
5x=17 subtract 7 from both sides
x=17/5 divide each side by 5

1) 4x - 34 + 4 = - 9 - 3x
4x - 30 = - 9 - 3x
7x = 21
x=3
2) 5x = 15
x = 3

#1
2(2x - 17) + 4 = -3(3 + x)
4x - 34 + 4 = -9 -3x
4x - 30 = -9 - 3x
7x = 21
x = 3
#2
5x + 7 = 22
5x = 15
x = 3
hope you can follow this and learn how to do it. algebra is a necessary skill to have.

2(2x-17)+4=-3(3+x) do distributive property
4x-34+4=-9-3x combine like terms
4x-30=-9-3x try to get x by itself
+30 +30
. 4x=21-3x get x on one side
+3x +3x
7x=21 divide by 7 to get x
x=3
5x+7=22 try get x by itself
-7 -7
5x=15 divide by 5 to get x
x=3
