Introduction to two step equations with integers:
Solving two step equation with integers is nothing but solving the equations that has integers in two steps. just by simplifying the equations that involve integers and variables. here in resolving these two step equations with integers just we resolve the variables in the equations..The students will be able to solve one-step and two-step linear equations involving integers, fractions, and decimals. Let us see what is the two step equations with integers and the sample problems for two step equations.
Two Step Equations with Integers:
Solving Two-Step Equations - getting variable alone
1. Remove constant by adding opposite to both sides.
2. If variable is being divided by a number, multiply both sides by the number. If variable is being multiplied by a number, divide both sides by the number (remember dividing by a fraction is the same as multiplying by the reciprocal).Is this topic solving linear equations and inequalities hard for you? Watch out for my coming posts.
Example 1:
Simplify `X/3` + 3 = 12
`X/3` + 3 – 3 = 12 – 3
`X/3` + 3 – 3 = 12 – 3
`X/3` = 9
`X/3` = 9
`X/3` · 3 = 9 ·3
X = `9*3`
X = 27
Example 2:
Simplify 4X – 5 = 6
4X – 5 + 5 = 6 + 5
4X – 5 + 5 = 11
4X = 11
`(4X)/4` = `11/4`
`X` = `11/4`
X = 2.75.
Two Step Equations with Integers:
Example 3:
simplify -3- 9x = -21 keep the variables on one side and move the integers to other side.
-9x = -18 resolve by dividing
x = 2
Example 4:
simplify 20 + 4x = 25
4x = 25 - 20
4x = 5
x = 20.
Example 5:
simplify
5x + 7 =14 keep the variables on one side and move the integers to other side.
5x = 7
x = `7/5 `
=1.4
Example 6:
simplify
`2/3` x - `1/(2x)` + 3 =15 keep the variables on one side and move the integers to other side.
`1/(6x)` + 3 =15
`1/(6x)` =12
x = 72
Example 7:
11=`2/(7m)` + 9
`11(7)` =`2/7` (7/1)m+9(7) Multiply each term by the Least Common Denominator (LCD)(7).
77-63 = 2m+63-63 Subtract 63 from both sides.
14/2 = `(2m)/2` Divide both coefficients by two
7=m
