When the bases are the same you add the exponents
-5+3 ==-2
7^-2 or. 1/49
x = 6
given + =
to eliminate the fractions multiply through by the lowest common multiple of x, 3 and 6 , that is 6x
multiply all terms by 6x gives
18 + 2x = 5x ( subtract 2x from both sides )
18 = 3x ( divide both sides by 3 )
6 = x
As a check
+ = + =
Answer:
y=(-4/3)x-1
Step-by-step explanation:
Slope or m=-4/3
Y-intercept or b=-1
Putting in the standard equation y=mx+b
y=(-4/3)x+(-1)
y=(-4/3)x-1
