It would be: 2x+4 = 19 and the value of x works out as 7.5
what is the value of 4 in the number 294,506,893,613
Oops! That's not an equation. It has no 'equals' sign ( ' = ' ) in it, so it's just an 'expression' that stands for a number. The number that it stands for depends on the value of 'x', and any time 'x' changes, the value of the expression changes.

the number is represented by "x"8+ 4x= 4-8 -84x=-44 4x=-1Check: 8+ 4( x)= 48+ 4(-1)= 48+ (-4)= 48-4= 4
A square number is the product of a number and itself. 16 is square; it is the product of 4 and 4; 4 times 4.
(-4) + (+8) is +4
no number; absolute value is always positive. The absolute value of a negative number is positive. For example absolute value of -4 is +4
