It should be evaluated as a major calculation error!
It is: 8+7 = 15
Addition
Since 7x + 13x +2x + 8 is an expression (there is no equal sign), there is no answer as to what x equals. However, this expression can be simplified to 22x + 8.
Use a calculator, or just the addition techniques taught to you in 1st grade.
6 + 12 - 5 = 13

Given a value of x, find the value for -3x + 2
Though 10x +24 is an expression and it can not be evaluate, we can write 10x+24=2 • (5x + 12)
7(3y-2)-(-4y+9)

This would be an expression if it didn't have an equals sign.
-5.6000000000000005
There is no variable in (8x12)+8, so it would be called an arithmetic expression. It would evaluate to 96+8 = 104.
To evaluate the expression (3xy + 4y^3) when (y = 2) and (x = 5), substitute the values into the expression. This gives: [ 3(5)(2) + 4(2^3) = 30 + 4(8) = 30 + 32 = 62. ] Thus, the value of the expression is 62.
