Well, take a look at this
-10x + 3 = -x + 21
+ 10 x +10x
--------------------------
3 = 9x + 21
-21 -21
---------------------
-18 = 9x
-2 = x
hope this helps

Answer:
Step-by-step explanation:
y = 5x - 43.....slope is 5
a parallel line will have the same slope
(-6,0)...x = -6 and y = 0
slope(m) = 5
y = mx + b
0 = 5(-6) + b
0 = -30 + b
30 = b
so ur parallel equation is : y = 5x + 30
First you add like terms which means you add all the x's together and all the constants.
3x -5 =55 (Remember that 8 has a negative sign in front which brings that sign with it when combinding like terms)
Then you isolate the variable by adding 5 on both sides.
3x = 60.
Finally you divide by 3 on both sides to get x=20
