What does "perform the inverse mean" when referring to solving equations?
Performing the opposite operation to both sides of the equals sign.
The opposite of addition is subtraction, the opposite of multiplication is division and vice versa
3 = -2 – x
x= -5
x/2 -3=-8
x= -10
Solving Equations
2(n+5) = 4
n = -3
Solving Equations
-45 = (2x - 4)/4
x = -88
What does "solve" require as a solution in solving equations?
a variable on one side of the equals sign and a number on the other side
-5x = -80
x= 16
x/2-50=10
x= 120
Solving Equations
5(m-3) = 4
m = 3.8
Solving Equations
4 = (7a - 8)/12
a=8
When rounding to two decimal places, what number would I look at if I was to round 23.83465831 and what would my answer be?
When rounding to two decimal places, I would look at the third number after the decimal point. It is the number "4". This requires my solution to be rounded to 23.83
-16 = x+2
x= -18
x/3+16=-3
x= -57
Solving Equations
