One & Two Step Equations
h – 2 = 0
h = 2
5(a - 1) = 35
a = 8
Solve for p:
(p – k) / j = n
p = jn + k
Write an Equation:
“nine more than the quotient of twenty-four and a number”
24/x + 9
Every equation contains this...
an equal sign "="
2n = -32
n = -16
4b + 16 + 2b = 46
b = 5
Solve for x:
y=mx + b
x = (y – b)/m
The Braves played a 9 inning baseball game. Every inning they scored 1 run, and for every 3 runs they scored, they had 5 hits. How many hits did they have during the game?
15 hits
Solve for y:
xyz=3p
y = 3p/xz
- 5j + 8 = 23
j = -3
12 = 6(5 - a)
a = 3
Solve for p:
a = b + cp
p = (a - b)/c
It costs about $30 per person to go kayaking for the day at Peace Valley park. If everyone in a group pays the same amount and the total bill came to $450, how many people in the group went kayaking?
15 people
11m – (6m – 5) = 25
m = 6
- 6 + 10v = 44
v = 5
15 +q/6= 21
q = 36
Solve for a:
a/b – 8 = c
a = b(c + 8)
or
a = bc + 8c
The price of a car tire has been reduced by $15. You buy 4 tires for $600. Find the original price of one tire.
Original Price = $165
3 – n = -4
7 7 7
n = 7
(3 – n)= -4
7
n = 31
–15 = 5(3q – 10) – 5q
q = 3.5
Solve for n:
m – n = p
-5
n = 5p + m
An office manager spent $650 on a new energy-saving copier that will reduce the monthly electric bill for the office from $112 to $88. In how many months will the copier pay for itself?
In about 28 months
m = 27.08 so technically you would need 28 months to pay off the energy saving copier
Solve for x:
4x – a = 9x + b
x = -a – b
