Answer:
x=1
Step-by-step explanation:
5x+2=3x+4(2x-1)
First take the ( ) 4*2xand 4*-1
Then simplify and add all like terms
then subtract/add(opposite of what it is) whichever x term from both sides
then subtract/add the numbers on the side you chose to the other side to get something as the following
x=#
then divide x by the #
Answer:
x = 9
Step-by-step explanation:
Sum of all angles of a triangle = 180
63 + 7x + 6x = 180
63 + 13x =180
13x = 180 - 63
13x = 117
x = 117/13
x = 9
