10
There are 2 unknowns
2x - 4 = -10 2x = -10 +4 2x = -6 x = -3
Multiply first equation by 2: 4x - 2y = 20 Subtract second equation: x = 12, so y = 14.
It is an equation and the value of x works out as 88
10
An equation?
The equation is -2y + 16 = 10
If a statement includes an "equals" sign ( = ) then the statement is an equation. By the way . . . it may or may not be a true statement. "10 equals 120" is not true.
That word "equals" in there makes it an equation.
a=10
An equation where c = 5
an equation
Divide each side of the equation by 10 .
An equation never equals a number, but its solution often does.-- An equation with a solution of six: [ 3x - 14 = 4 ]-- An equation with a solution of three: [ 14 - 10x = -16 ]-- An equation with both solutions: [ x2 - 9x + 20 = 2 ]An equation that equals 6 is 10 - 4 = 6An equation that equals 3 is 10 - 7 = 3
-2x + 8 = 7x - 10 is technically an equation, in and of itself.
