Question

write an equivalent expression for 28x+14+4x+16 if x equals 4 is the solution to both of the expressions the same?

Answer 1

Sub in 4 for x and multiply so it would be 112 + 30 + 16 which is 158

Answer 2

Answer: The solution of both the expressions are same which is 158

Step-by-step explanation:

Like terms are defined as the terms which have same variable. Mathematical operation are applied on these terms.

Unlike terms are defined as the terms which do not have same variable. Mathematical operation are not applied on these terms.

We are given an expression:

$28x+14+4x+16$       .......(1)

Simplifying the above expression, we get:

$\Rightarrow 32x+30$     .......(2)

We are given:

Value of x = 4

Putting this in expression 1, we get:

$\Rightarrow (28\times 4)+14+(4\times 4)+16=158$

Putting this in expression 2, we get:

$\Rightarrow (32\times 4)+30=158$

Hence, the solution of both the expressions are same which is 158
