Solve equations by using inverse operations to transform both sides of the equation
in the same way.
x and ÷
+ and -
Name at least three careers where you would need to use equations
(excluding teaching!)
Solve, equation, bracket, inverse, denominator
Skill Practice
1) Solve these equations
Stretch
3b = 12
2 + y = 3
32 = 10
3x + 9 = 5 2
2p – 4 = 3p
22 – 3a = 4a - 6
The sides of a square are 2x +1 cm and 21 – 3x in length.
Find the value of x, and hence the area and perimeter of the square 2 9
2x + 1
d - 2
21-3x
2) Solve equations involving brackets
3(m + 2) = 3 5
8(n – 1) = 3n – 4
Homework effort 10
3)The answer to the equation x3 – 2x = 88 lies between 4 and 5 Solve by trial and error to 1 d.p.
