Addition
33 + a = 76
a = 43
t - 5 = 4
t = 9
What's the inverse operation of subtraction?
Addition
5a = 25
a = 5
a/9 = 9
a = 81
12 = 8 + y
4 = y
130 = a - 100
230 = a
In an equation, what are you trying to do to the variable?
Find the value of the variable
625 = 25a
25 = a
1/7 a = 4
a = 28
a + 21 = 42.5
a = 21.5
a-10.25 = 18.75
a = 29
x/3 = 1/4
What would be the first step to solving the equation?
multiply both sides by 3
1.8x = 486
x = 270
a/10 = 4
a = 40
r + 1/3 = 4/6
r = 1/3
w - 15= 95
w = 110
Word used for the term that stands alone without a coefficient in an equation or expression.
Constant
3/4p = 12
p = 16
7/8k = 21
k = 24
12.01 + b = 36.1
b = 24.09
1,824.8 = h - 1,208.007
h = 3032.807
When you know your answer is correct, you have done this.
Checked the solution works in the original equation.
0.8s = 2.4
s = 3
2/9 = 4/5m
10/36 or 5/18 = m
