x-7+x is also the same as 2x-7
2x-7 = 53
53+7 = 2x
60 = 2x
x = 30

Collet like terms to 2x-7=53. then add 7 to both sides so the the 7's on the left cancel out 2x=60. divide 2 to both sides. x=30

x -7+x = 53
x + x = 53 + 7
2x = 60
x = 60/2
x = 30

x-7+x=53
+7 +7
first you add the seven to both sides (there is a minus sign in front of the seven, since you want to cancel it out, you must add it), since you always want to get the x by itself. you must always do the same thing to bothe sides of the equation. this gives you
x+x=60
since the x's are like terms, you can combine them to get
2x=60
/2 /2
becuase you want to find the value of x, you have to divide both sides by 2 and get
x=30

7(3 - x) = 8(4 - 2x) : original Distribute first : 21 - 7x = 32 - 16x Add 16x : 21 + 9x = 32 Subtract 21 : 9x = 11 Divide by 9 : x = 11/9 -- or answer (d)
