Both expressions illustrate the use of algebraic expressions.
The missing term of -46x + 18 is 2
The expressions are given as:
-4(12x - 5) + 2x and -46x + 18
Let the first term of -46x + 18 be represented with variable y.
So, we have:
y -46x + 18
Equate both expressions
[tex]-4(12x - 5) + 2x = y -46x + 18[/tex]
Open brackets
[tex]-48x + 20 + 2x = y -46x + 18[/tex]
Collect like terms
[tex]y = 46x - 48x + 2x + 20 - 18[/tex]
[tex]y = 0 + 2[/tex]
[tex]y = 2[/tex]
Hence, the missing term is 2
