Solve for x. 3X - 4 3X - 8
1 answer:
Answer:
x = 2
As x = 12/6 = 2
Step-by-step explanation:
3x-4+3x-8
3x+3x-4-8
= 6x-12
FACTORISING for check and set to zero
6(x-2)
6x -12 = 0
Cancel out left by adding 12 to both sides then applying /6 to both sides to cancel 6 left side.
6x--12 + 12 = 0 + 12
6x / 6 = 12 / 6
x = 12/6
x = 2
or balance as grouping by separation = multiply at end by -1
3x+3x = --4 - 8
6x = - 12
x = - 12/6
x = - 2
x = - 2 ( -1 )
x = 2

The equivalent expressions are 2(24m + 21n) and 3(16m + 14n) and 6(8m + 7n)
<em><u>Solution:</u></em>
Given that, we have to factor the given expression
<em><u>Given expression is:</u></em>
48m + 42n
The equivalent expressions can be found by factoring out the common factors of 48 and 42
<em><u>Let us first find the factors of 48 and 42</u></em>
The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, 42
The factors of 48 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
Thus the common factors are: 1, 2, 3, 6
Let us factor out 2 from given expression
Now factor out 3 from given expression
Now factor out 6 from given expression
Thus the equivalent expressions are 2(24m + 21n) and 3(16m + 14n) and 6(8m + 7n)
