(1,3)
Step-by-step explanation:
12. 4x - 1
I’m not sure with 13 & 14
6x+3x+8=35
Step 1: Simplify both sides of the equation.
6x+3x+8=35
(6x+3x)+(8)=35(Combine Like Terms)
9x+8=35
9x+8=35
Step 2: Subtract 8 from both sides.
9x+8−8=35−8
9x=27
Step 3: Divide both sides by 9.
9x
9
=
27
9
x=3
Answer:
x=3
12w−5−3w=40
Step 1: Simplify both sides of the equation.
12w−5−3w=40
12w+−5+−3w=40
(12w+−3w)+(−5)=40(Combine Like Terms)
9w+−5=40
9w−5=40
Step 2: Add 5 to both sides.
9w−5+5=40+5
9w=45
Step 3: Divide both sides by 9.
9w
9
=
45
9
w=5
Answer:
w=5
Answer:
x = - 1
Step-by-step explanation:
Length ( l ) = 2x + 8 cm
Width / Breadth ( b ) = 2 cm
Area ( rectangle ) = 12 cm
Formula : -
Area ( rectangle ) = lb
12 = ( 2x + 8 ) ( 2 )
Divide 2 on both sides,
12 / 2 = ( 2x + 8 ) ( 2 ) / 2
6 = 2x + 8
2x + 8 = 6
2x = 6 - 8
2x = - 2
x = - 2 / 2
x = - 1
