20*2+1+3/9=7
need to add grouping symbols to make it true

(20*(2+1)+3)/9 = 7

Step-by-step explanation:

You can tell that the only way that it can be true is using the division.

63/9 = 7

So I tried to find a way for everything before the grouping symbol to be 63:

(20*(2+1)+3)/9 = 7

none.

step-by-step explanation:

b=-1

find the slope and y-intercept of the second equation.

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
